SphinxAutocompleteExample

These samples illustrate autocomplete and type suggestion using Manticore/Sphinx search.
Querying is made via SphinxQL using PDO driver.
The sample data included contains a version of Sphinx documentation.
The samples are featured on [this Sphinx blog post] (http://sphinxsearch.com/blog/2013/05/21/simple-autocomplete-and-correction-suggestion/).

Requirements :

LAMP
Manticore or Sphinx search
PHP with PDO mysql

Installation :

Edit scripts/sphinx.conf for setting proper paths and db credentials Import the sample tables in your database.
Untar first the two archieves in scripts folder:

$ tar -xzvf suggest.tar.gz 
$ tar -xzvf docs.tar.gz
$ mysql < suggest.sql
$ mysql < docs.sql

Alternative you can build the suggest table by following instructions in scripts/suggest/README

The samples use 3 indexes : simplecompletefull for doing the actual search, simplecomplete for autocomplete and suggest for suggestions.
simpletecompletefull can be used for autocomplete as well, if the search for completion is made only on title ( @title $query ).
Index the 3 indexes:

$ indexer -c /path/to/sphinx.conf --all

Start a new Manticore/Sphinx server using sphinx.conf from scripts folder or import the indexes if you already have a running Sphinx server.

$ searchd -c /path/to/sphinx.conf

In case you start a new Manticore/Sphinx server, be sure to change the ports in sphinx.conf and common.php. In common.php edit the database credentials. For Sphinx 2.1.1 or greater/Manticore or trunk version, set constant SPHINX_20 to false.
Autocomplete starts after typing 3 characters. To change this you need to edit in sphinx.conf min_prefix_len and min_word_len and in footer.php and footer_excerpts.php the minLength ( which trigger firing the ajax call).
