The advanced search finder deviates slightly from the classic abstract finder-frontend patterns to accommodate filtering by taxons, content_purpose_supergroups and content_purpose_subgroups.
The need for this arises from larger volumes of content being tagged to the taxonomy and filtering content-rich taxons by content types provides an effective mechanism to searching across a topic.
topic(Required) - Alias for rummager search parametertaxons. Filters results to content tagged to the specified taxon path. eg.topic=/education.group(Required) - Alias for rummager search parametercontent_purpose_supergroup. Instead of pre-defined facets, the publication type filters are populated from the govuk_document_types gem based on thegroupparameter.subgroup(Optional) - Alias for rummager search parametercontent_purpose_subgroup. This optional parameter narrows the content filter to specific types of content. The parameter obeys the Rails convention of array parameters. eg.subgroup[]=news&subgroup[]=updates_and_alerts.
Without the required parameters, this responds with 404.
The advanced search finder is available at the path /search/advanced. The underlying content item is published via a rake task in Rummager.
The advanced search finder uses much of the facet filtering abilities of the finder-frontend, the subgroup facet values are loaded dynamically depending on the parent group (content_purpose_supergroup) parameter. The group and subgroup definitions are stored in govuk_document_types.
The advanced search finder has a distinct controller, api service class and query builder to provide the necessary functionality without affecting or compromising the original finder codebase.
