Neos Elasticsearch Adapter

This project connects the Neos Content Repository to Elasticsearch; enabling two main functionalities:

finding Nodes in Fusion / Eel by arbitrary queries
Full-Text Indexing of Pages and other Documents (of course including the full content)

This documentation is structured in the following parts:

Installation: Which packages are needed and how they are installed.
Commands: This section describes the available ./flow CLI commands
Configuration: Configuration of indices, fields, ...
Query Data: Available Eel operations to query data
Examples: Some more advanced examples

Installation

composer require 'flowpack/elasticsearch-contentrepositoryadaptor'
// Not required, but can be used to learn how to integration the flowpack/elasticsearch-contentrepositoryadaptor in your project
composer require 'flowpack/searchplugin'

Ensure to update <your-elasticsearch>/config/elasticsearch.yml as explained below; then start Elasticsearch.

Finally, run ./flow nodeindex:build, and add the search plugin to your page. It should "just work".

Relevant Packages

Neos.ContentRepository.Search: provides common functionality for searching Neos Content Repository nodes. Does not contain a search backend.
Flowpack.ElasticSearch: provides common code for working with Elasticsearch
Flowpack.ElasticSearch.ContentRepositoryAdaptor: this package
Flowpack.SimpleSearch.ContentRepositoryAdaptor: an alternative search backend (to be used instead of this package); storing the search index in SQLite
Flowpack.SearchPlugin: search plugin for Neos

Elasticseearch version support

HINT: this package only supports modern versions of Elasticsearch. If you need 1.x or 2.x support, please see the 4.x branch of this repository.

You can switch the Elasticsearch driver by editing Settings.yaml (Flowpack.ElasticSearch.ContentRepositoryAdaptor.driver.version) with the following value:

5.x to support Elasticsearch 5.x

Currently the Driver interfaces are not marked as API, and can be changed to adapt to future needs.

Elasticsearch Configuration file elasticsearch.yml

The following general configuration advice can make your life easier:

# the following settings secure your cluster
cluster.name: [PUT_YOUR_CUSTOM_NAME_HERE]
node.name: [PUT_YOUR_CUSTOM_NAME_HERE]
network.host: _local_

There may be a need, to add specific configuration to your Elasticsearch Configuration File <your-elasticsearch>/config/elasticsearch.yml, , depending on your version of Elasticsearch.

Elasticsearch 5.x

Commands

Building up the index

The node index is updated on the fly, but during development you need to update it frequently.

In case of a mapping update, you need to reindex all nodes. Don't worry to do that in production; the system transparently creates a new index, fills it completely, and when everything worked, changes the index alias.

./flow nodeindex:build

if during development, you only want to index a few nodes, you can use "limit"

./flow nodeindex:build --limit 20

Cleanup old indices

In order to remove old, non-used indices, you should use this command from time to time:

./flow nodeindex:cleanup

Debug commands

The following commands are meant to be used for debugging while configuring and developing your search:

./flow nodeindexmapping:indices

Shows the mapping between the projects dimensions presets and the resultig index name.

./flow nodeindexmapping:mapping

Shows the mapping created for the NodeTypes.

./flow search:viewnode <nodeIdentifier>

Shows all contents that are indexed fo a given node.

./flow search:fulltext

Performs a fulltext search and displays the results.

Configuration

Index Settings

If you want to fine-tune the indexing and mapping on a more detailed level, you can do so in the following way.

Configure the index name

If you need to run serveral (different) neos instances on the same elasticsearch server you will need to change the Configuration/Settings.yaml indexName for each of your project.

So ./flow nodeindex:build or ./flow nodeindex:cleanup won't overwrite your other sites index.

Neos:
  ContentRepository:
    Search:
      elasticSearch:
        indexName: useMoreSpecificIndexName

If you use multiple client configurations, please change the default key just below the indexes.

Configure per index

You can set one default configuration for all indices with your index prefix.

Flowpack:
  ElasticSearch:
    indexes:
      default: # Configuration bundle name
        neoscontentrepository: # The index prefix name, must be the same as in the Neos.ContentRepository.Search.elasticSearch.indexName setting
          index:
            number_of_shards: 1
            number_of_replicas: 0

Configure per dimension

As an index is created for every dimension combination of the Neos content repository, you can configure the index behavior for every dimension combination separately.

Caution: Default configuration and per dimension combination configuration is not merged. If a configuration for a dimension-combination is found, this configuration is used.

Flowpack:
  ElasticSearch:
    indexes:
      default: 
        'neoscontentrepository-0359ed5c416567b8bc2e5ade0f277b36': # The hash specifies the dimension combination 
          index:
            number_of_shards: 1
            number_of_replicas: 0
          analysis:
            filter:
              elision:
                type: 'elision'
                articles: [ 'l', 'm', 't', 'qu', 'n', 's', 'j', 'd' ]
            analyzer:
              custom_french_analyzer:
                tokenizer: 'letter'
                filter: [ 'asciifolding', 'lowercase', 'french_stem', 'elision', 'stop' ]
              tag_analyzer:
                tokenizer: 'keyword'
                filter: [ 'asciifolding', 'lowercase' ]

Which dimension combinations are available in your system and which hashes they are identified with can be shown with the CLI command:

dflow nodeindexmapping:indices

Configurations per property (index field)

Then, you can change the analyzers on a per-field level; or e.g. reconfigure the _all field with the following snippet in the NodeTypes.yaml. Generally this works by defining the global mapping at [nodeType].search.elasticSearchMapping:

'Neos.Neos:Node':
  search:
    elasticSearchMapping:
      myProperty:
        analyzer: custom_french_analyzer

Exclude NodeTypes from indexing

By default the indexing processes all NodeTypes, but you can change this in your Settings.yaml:

Neos:
  ContentRepository:
    Search:
      defaultConfigurationPerNodeType:
        '*':
          indexed: true
        'Neos.Neos:FallbackNode':
          indexed: false
        'Neos.Neos:Shortcut':
          indexed: false
        'Neos.Neos:ContentCollection':
          indexed: false

You need to explicitly configure the individual NodeTypes (this feature does not check the Super Type configuration). But you can use a special notation to configure a full namespace, Acme.AcmeCom:* will be applied for all node types in the Acme.AcmeCom namespace. The most specific configuration is used in this order:

NodeType name (Neos.Neos:Shortcut)
Full namespace notation (Neos.Neos:*)
Catch all (*)

Advanced Indexing configuration

Indexing configuration per data type

The default configuration supports most usecases and often may not need to be touched, as this package comes with sane defaults for all Neos data types.

Indexing of properties is configured at two places. The defaults per-data-type are configured inside Neos.ContentRepository.Search.defaultConfigurationPerType of Settings.yaml. Furthermore, this can be overridden using the properties.[....].search path inside NodeTypes.yaml.

This configuration contains two parts:

Underneath elasticSearchMapping, the Elasticsearch property mapping can be defined.
Underneath indexing, an Eel expression which processes the value before indexing has to be specified. It has access to the current value and the current node.

Example (from the default configuration):

 # Settings.yaml
Neos:
  ContentRepository:
    Search:
      defaultConfigurationPerType:

        # strings should just be indexed with their simple value.
        string:
          elasticSearchMapping:
            type: string
          indexing: '${value}'

Indexing configuration per property

 # NodeTypes.yaml
'Neos.Neos:Timable':
  properties:
    '_hiddenBeforeDateTime':
      search:

        # a date should be mapped differently, and in this case we want to use a date format which
        # Elasticsearch understands
        elasticSearchMapping:
          type: DateTime
          format: 'date_time_no_millis'
        indexing: '${(node.hiddenBeforeDateTime ? Date.format(node.hiddenBeforeDateTime, "Y-m-d\TH:i:sP") : null)}'

If your nodetypes schema defines custom properties of type DateTime, you have got to provide similar configuration for them as well in your NodeTypes.yaml, or else they will not be indexed correctly.

There are a few indexing helpers inside the Indexing namespace which are usable inside the indexing expression. In most cases, you don't need to touch this, but they were needed to build up the standard indexing configuration:

Indexing.buildAllPathPrefixes: for a path such as foo/bar/baz, builds up a list of path prefixes, e.g. ['foo', 'foo/bar', 'foo/bar/baz'].
Indexing.extractNodeTypeNamesAndSupertypes(NodeType): extracts a list of node type names for the passed node type and all of its supertypes
Indexing.convertArrayOfNodesToArrayOfNodeIdentifiers(array $nodes): convert the given nodes to their node identifiers.

Fulltext Indexing

In order to enable fulltext indexing, every Document node must be configured as fulltext root. Thus, the following is configured in the default configuration:

'Neos.Neos:Document':
  search:
    fulltext:
      isRoot: true

A fulltext root contains all the content of its non-document children, such that when one searches inside these texts, the document itself is returned as result.

In order to specify how the fulltext of a property in a node should be extracted, this is configured in NodeTypes.yaml at properties.[propertyName].search.fulltextExtractor.

An example:

'Neos.Neos.NodeTypes:Text':
  properties:
    'text':
      search:
        fulltextExtractor: '${Indexing.extractHtmlTags(value)}'

'My.Blog:Post':
  properties:
    title:
      search:
        fulltextExtractor: '${Indexing.extractInto("h1", value)}'

Working with Dates

As a default, Elasticsearch indexes dates in the UTC Timezone. In order to have it index using the timezone currently configured in PHP, the configuration for any property in a node which represents a date should look like this:

'My.Blog:Post':
  properties:
    date:
      search:
        elasticSearchMapping:
          type: 'date'
          format: 'date_time_no_millis'
        indexing: '${(value ? Date.format(value, "Y-m-d\TH:i:sP") : null)}'

This is important so that Date- and Time-based searches work as expected, both when using formatted DateTime strings and when using relative DateTime calculations (eg.: now, now+1d).

If you want to filter items by date, e.g. to show items with date later than today, you can create a query like this:

${...greaterThan('date', Date.format(Date.Now(), "Y-m-d\TH:i:sP"))...}

For more information on Elasticsearch's Date Formats, click here.

Working with Assets / Attachments

If you want to index attachments, you need to install the Elasticsearch Attachment Plugin. Then, you can add the following to your Settings.yaml:

Neos:
  ContentRepository:
    Search:
      defaultConfigurationPerType:
        'Neos\Media\Domain\Model\Asset':
          elasticSearchMapping:
            type: attachment
          indexing: ${Indexing.indexAsset(value)}

        'array<Neos\Media\Domain\Model\Asset>':
          elasticSearchMapping:
            type: attachment
          indexing: ${Indexing.indexAsset(value)}

Query Data

We'll first show how to do arbitrary Elasticsearch Queries in Fusion. This is a more powerful alternative to FlowQuery. In the long run, we might be able to integrate this API back into FlowQuery, but for now it works well as-is.

Generally, Elasticsearch queries are done using the Search Eel helper. In case you want to retrieve a list of nodes, you'll generally do:

nodes = ${Search.query(site)....execute()}

In case you just want to retrieve a single node, the form of a query is as follows:

nodes = ${q(Search.query(site)....execute()).get(0)}

To fetch the total number of hits a query returns, the form of a query is as follows:

nodes = ${Search.query(site)....count()}

All queries search underneath a certain subnode. In case you want to search "globally", you will search underneath the current site node (like in the example above).

Furthermore, the following operators are supported:

As value, the following methods accept a simple type, a node object or a DateTime object.

nodeType('Your.Node:Type')
exactMatch('propertyName', value) -- supports simple types: exactMatch('tag', 'foo'), or node references: exactMatch('author', authorNode)
exclude('propertyName', value) -- excludes results by property - the negation of exactMatch.
greaterThan('propertyName', value, [clauseType]) -- range filter with property values greater than the given value
greaterThanOrEqual('propertyName', value, [clauseType]) -- range filter with property values greater than or equal to the given value
lessThan('propertyName', value, [clauseType]) -- range filter with property values less than the given value
lessThanOrEqual('propertyName', value, [clauseType]) -- range filter with property values less than or equal to the given value
sortAsc('propertyName') and sortDesc('propertyName') -- can also be used multiple times, e.g. sortAsc('tag').sortDesc(date')` will first sort by tag ascending, and then by date descending.
limit(5) -- only return five results. If not specified, the default limit by Elasticsearch applies (which is at 10 by default)
from(5) -- return the results starting from the 6th one
fulltext('searchWord', options) -- do a query_string query on the Fulltext index using the searchword and additional options to the query_string

moreLikeThis(like, fields, options)

The More Like This Query (MLT Query) finds documents that are "like" a given text or a given set of documents.

like Single value or an array of strings or nodes.
fields An array of fields which are used to compare other docs with the given "like" definition.
options Additional options for the more_like_this query. See the elasticsearch documentation for what is possible.

Low-level operations

Furthermore, there is a more low-level operator which can be used to add arbitrary Elasticsearch filters:

queryFilter("filterType", {option1: "value1"}, [clauseType])

The optional argument clauseType defaults to "must" and can be used to specify the boolean operator of the bool query. It has to be one of must, should, must_not or filter.

At lowest level, there is the request operator which allows to modify the request in arbitrary manner. Note that the existing request is merged with the passed-in type in case it is an array:

request('query.filtered.query.bool.minimum_should_match', 1)
request('query.filtered.query.bool', {"minimum_should_match": 1})

In order to debug the query more easily, the following operation is helpful:

log() log the full query on execution into the Elasticsearch log (i.e. in Data/Logs/ElasticSearch.log)

Example Queries

Finding all pages which are tagged in a special way and rendering them in an overview

Use Case: On a "Tag Overview" page, you want to show all pages being tagged in a certain way

Setup: You have two node types in a blog called Acme.Blog:Post and Acme.Blog:Tag, both inheriting from Neos.Neos:Document. The Post node type has a property tags which is of type references, pointing to Tag documents.

Fusion setup:

 # for "Tag" documents, replace the main content area.
prototype(Neos.Neos:PrimaryContent).acmeBlogTag {
    condition = ${q(node).is('[instanceof Acme.Blog:Tag]')}
    type = 'Acme.Blog:TagPage'
}

 # The "TagPage"
prototype(Acme.Blog:TagPage) < prototype(Neos.Fusion:Collection) {
    collection = ${Search.query(site).nodeType('Acme.Blog:Post').exactMatch('tags', node).sortDesc('creationDate').execute()}
    itemName = 'node'
    itemRenderer = Acme.Blog:SingleTag
}
prototype(Acme.Blog:SingleTag) < prototype(Neos.Neos:Template) {
    ...
}

Making OR queries

There's no OR operator provided in this package, so you need to use a custom Elasticsearch query filter for that:

....queryFilter('bool', {should: [
    {term: {tags: tagNode.identifier}},
    {term: {places: tagNode.identifier}},
    {term: {projects: tagNode.identifier}}
]})

Aggregations

Aggregation is an easy way to aggregate your node data in different ways. Elasticsearch provides a couple of different types of aggregations. Check https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations.html for more info about aggregations. You can use them to get some simple aggregations like min, max or average values for your node data. Aggregations also allows you to build a complex filter for e.g. a product search or statistics.

Aggregation methods Right now there are two methods implemented. One generic aggregation function that allows you to add any kind of aggregation definition and a pre-configured fieldBasedAggregation. Both methods can be added to your TS search query. You can nest aggregations by providing a parent name.

aggregation($name, array $aggregationDefinition, $parentPath = NULL) -- generic method to add a $aggregationDefinition under a path $parentPath with the name $name.
fieldBasedAggregation($name, $field, $type = 'terms', $parentPath = '', $size = 10) -- adds a simple filed based Aggregation of type $type with name $name under path $parentPath. Used for simple aggregations like sum, avg, min, max or terms. By default 10 buckets are returned.

Examples

Aggregations

Add a average aggregation

To add an average aggregation you can use the fieldBasedAggregation. This snippet would add an average aggregation for a property price:

nodes = ${Search.query(site)...fieldBasedAggregation("avgprice", "price", "avg").execute()}

Now you can access your aggregations inside your fluid template with

{nodes.aggregations}

Create a nested aggregation

In this scenario you could have a node that represents a product with the properties price and color. If you would like to know the average price for all your colors you just nest an aggregation in your Fusion:

nodes = ${Search.query(site)...fieldBasedAggregation("colors", "color").fieldBasedAggregation("avgprice", "price", "avg", "colors").execute()}

The first fieldBasedAggregation will add a simple terms aggregation (https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html) with the name colors. So all different colors of your nodetype will be listed here. The second fieldBasedAggregation will add another sub-aggregation named avgprice below your colors-aggregation.

You can nest even more aggregations like this:

fieldBasedAggregation("anotherAggregation", "field", "avg", "colors.avgprice")

Add a custom aggregation

To add a custom aggregation you can use the aggregation() method. All you have to do is to provide an array with your aggregation definition. This example would do the same as the fieldBasedAggregation would do for you:

aggregationDefinition = Neos.Fusion:RawArray {
    terms = Neos.Fusion:RawArray {
        field = "color"
    }
}
nodes = ${Search.query(site)...aggregation("color", this.aggregationDefinition).execute()}

Product filter

This is a more complex scenario. With this snippet we will create a full product filter based on your selected Nodes. Imagine an NodeTye ProductList with an property products. This property contains a comma separated list of sku's. This could also be a reference on other products.

prototype(Vendor.Name:FilteredProductList) < prototype(Neos.Neos:Content)
prototype(Vendor.Name:FilteredProductList) {

    // Create SearchFilter for products
    searchFilter = Neos.Fusion:RawArray {
        sku = ${String.split(q(node).property("products"), ",")}
    }

    # Search for all products that matches your queryFilter and add aggregations
    filter = ${Search.query(site).nodeType("Vendor.Name:Product").queryFilterMultiple(this.searchFilter, "must").fieldBasedAggregation("color", "color").fieldBasedAggregation("size", "size").execute()}

    # Add more filter if get/post params are set
    searchFilter.color = ${request.arguments.color}
    [email protected] = ${request.arguments.color != ""}
    searchFilter.size = ${request.arguments.size}
    [email protected] = ${request.arguments.size != ""}

    # filter your products
    products = ${Search.query(site).nodeType("Vendor.Name:Product").queryFilterMultiple(this.searchFilter, "must").execute()}

    # don't cache this element
    @cache {
        mode = 'uncached'
        context {
            1 = 'node'
            2 = 'site'
        }
    }

In the first lines we will add a new searchFilter variable and add your selected sku's as a filter. Based on this selection we will add two aggregations of type terms. You can access the filter in your template with {filter.aggregations}. With this information it is easy to create a form with some select fields with all available options. If you submit the form just call the same page and add the get parameter color and/or size. The next lines will parse those parameters and add them to the searchFilter. Based on your selection all products will be fetched and passed to your template.

Important notice

If you do use the terms filter be aware of Elasticsearchs analyze functionality for strings. You might want to disable this for all your filterable properties, or else filtering won't work on them properly:

'Vendor.Name:Product'
  properties:
    color:
      type: string
      defaultValue: ''
      search:
        elasticSearchMapping:
          type: "string"
          index: 'not_analyzed'

Note: When using Elasticsearch 5.x the mapping needs to be adjusted in a different way. More information on the mapping in ElasticSearch 5.x.

Sorting

This package adapts Elasticsearchs sorting capabilities. You can add multiple sort operations to your query. Right now there are three methods you can use:

sortAsc('propertyName')
sortDesc('propertyName')
sort('configuration')

Just append those method to your query like this:

# Sort ascending by property title

nodes = ${q(Search.query(site).....sortAsc("title").execute())}

# Sort for multiple properties

nodes = ${q(Search.query(site).....sortAsc("title").sortDesc("name").execute())}

# Custom sort operation

geoSorting = Neos.Fusion:RawArray {
    _geo_distance = Neos.Fusion:RawArray {
        latlng = Neos.Fusion:RawArray {
            lat = 51.512711
            lon = 7.453084
        }
        order = "plane"
        unit = "km"
        distance_type = "sloppy_arc"
    }
}
nodes = ${Search.query(site).....sort(this.geoSorting).execute()}

Check https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-sort.html for more configuration options.

Example with pagination and sort by distance

This is how a more complex example could look like. Imagine you a want to render a list of nodes and in addition to each node you want to display the distance to a specific point.

First of all you have to define a property in your NodeTypes.yaml for your node where to store lat/lon information's:

'Vendor.Name:Retailer':
  properties:
    'latlng':
      type: string
      search:
        elasticSearchMapping:
          type: "geo_point"

Query your nodes in your Fusion:

geoSorting = Neos.Fusion:RawArray {
    _geo_distance = Neos.Fusion:RawArray {
        latlng = Neos.Fusion:RawArray {
            lat = 51.512711
            lon = 7.453084
        }
        order = "plane"
        unit = "km"
        distance_type = "sloppy_arc"
    }
}
nodes = ${Search.query(site).nodeType('Vendor.Name:Retailer').sort(this.geoSorting)}

Now you can paginate that nodes in your template. To get your actually distance for each node use the GetHitArrayForNodeViewHelper:

{namespace cr=Neos\ContentRepository\Search\ViewHelpers}
{namespace es=Flowpack\ElasticSearch\ContentRepositoryAdaptor\ViewHelpers}

<cr:widget.paginate query="{nodes}" as="paginatedNodes">
    <f:for each="{paginatedNodes}" as="singleNode">
        {singleNode.name} - <es:getHitArrayForNode queryResultObject="{nodes}" node="{singleNode}" path="sort.0" />
    </f:for>
</cr:widget.paginate>

The ViewHelper will use \Neos\Utility\Arrays::getValueByPath() to return a specified path. So you can make use of an array or a string. Check the documentation \Neos\Utility\Arrays::getValueByPath() for more information.

Important notice

The ViewHelper GetHitArrayForNode will return the raw hit result array. The path property allows you to access some specific data like the the sort data. If there is only one value for your path the value will be returned. If there is more data the full array will be returned by GetHitArrayForNode-VH. So you might have to use the ForViewHelper to access your sort values.

Fulltext Search / Indexing

When searching in a fulltext index, we want to show Pages, or, generally speaking, everything which is a Document node. However, the main content of a certain Document is often not stored in the node itself, but inside its (Content) child nodes.

This is why we need some special functionality for indexing, which adds the content of the inner nodes to the Document nodes where they belong to, to a field called __fulltext and __fulltextParts.

Furthermore, we want that a fulltext match e.g. inside a headline is seen as more important than a match inside the normal body text. That's why the Document node not only contains one field with all the texts, but multiple "buckets" where text is added to: One field which contains everything deemed as "very important" (__fulltext.h1), one which is "less important" (__fulltext.h2), and finally one for the plain text (__fulltext.text). All of these fields are configured with different boost values.

For a search user interface, checkout the Flowpack.SearchPlugin package

Suggestions

Elasticsearch offers an easy way to get query suggestions based on your query. Check https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html for more information about how you can build and use suggestion in your search.

Suggestion methods implemented

There are two methods implemented. suggestions is a generic one that allows to build the suggestion query of your dreams. The other method is termSuggestions and is meant for basic term suggestions. They can be added to your totaly awesome TS search query.

suggestions($name, array $suggestionDefinition) -- generic method to be filled with your own suggestionQuery
termSuggestions($term, $field = '_all', $name = 'suggestions' -- simple term suggestion query on all fields

Examples

Add a simple suggestion to a query

Simple suggestion that returns a suggestion based on the sent term

suggestions = ${Search.query(site)...termSuggestions('someTerm')}

You can access your suggestions inside your fluid template with

{nodes.suggestions}

Add a custom suggestion

Phrase query that returns query suggestions

suggestionsQueryDefinition = Neos.Fusion:RawArray {
    text = 'some Text'
    simple_phrase = Neos.Fusion:RawArray {
        phrase = Neos.Fusion:RawArray {
            analyzer = 'body'
            field = 'bigram'
            size = 1
            real_world_error_likelihood = 0.95
            ...
        }
    }
}
suggestions = ${Search.query(site)...suggestions('my_suggestions', this.suggestionsQueryDefinition)}

Calculate the maximum cache time

In order to set the maximum cache time of a fusion prototype that renders nodes fetched by Search(), the nearest future value of the hiddenBeforeDateTime or hiddenAfterDateTime properties of all nodes in the result needs to be calculated.

prototype(Acme.Blog:Listing) < prototype(Neos.Fusion:Collection) {
    @context.searchQuery = ${Search.query(site).nodeType('Acme.Blog:Post')}

    collection = ${searchQuery.execute()}
    itemName = 'node'
    itemRenderer = Acme.Blog:Post
    
     @cache {
        mode = 'cached'
        maximumLifetime = ${searchQuery.cacheLifetime()}
        
        entryTags {
        map = ${'NodeType_Acme.Blog:Post'}

Debugging

In order to understand what's going on, the following might be helpful:

use ./flow nodeindex:showMapping to show the currently defined Elasticsearch Mapping
use the .log() statement inside queries to dump them to the Elasticsearch Log
the logfile Data/Logs/ElasticSearch.log contains loads of helpful information.

Settings.yaml

Change the base namespace for configuration from Flowpack.ElasticSearch.ContentRepositoryAdaptor to Neos.ContentRepository.Search. All further adjustments are made underneath this namespace:
(If it exists in your configuration:) Move indexName to elasticSearch.indexName
(If it exists in your configuration:) Move log to elasticSearch.log
search for mapping (inside defaultConfigurationPerType.<typeName>) and replace it by elasticSearchMapping.
Inside the indexing expressions (at defaultConfigurationPerType.<typeName>), replace ElasticSearch. by Indexing..

NodeTypes.yaml

Replace elasticSearch by search. This replaces both <YourNodeType>.elasticSearch and <YourNodeType>.properties.<propertyName>.elasticSearch.
search for mapping (inside <YourNodeType>.properties.<propertyName>.search) and replace it by elasticSearchMapping.
Replace ElasticSeach.fulltext by Indexing
Search for ElasticSearch. (inside the indexing expressions) and replace them by Indexing.
