This module provides a database based implementation of the Search API. The
database and target to use for storing and accessing the indexes can be selected
when creating a new server.
All Search API datatypes are supported by using appropriate SQL datatypes for
their respective columns (with "String"/"URI", and "Integer"/"Duration" being
equivalent).
The "direct" parse mode for queries will result in a simple splitting of the
query string into keys. Additionally, search keys containing whitespace will be
split, as searching for phrases is currently not supported.
Installation
- Install this module and its dependencies using the official
Backdrop CMS instructions
Configuration and Usage
Hidden configuration variables
autocomplete_max_occurrences(default: 0.9)
By default, keywords that occur in more than 90% of results are ignored for
autocomplete suggestions. This setting lets you modify that behaviour by
providing your own ratio. Use 1 or greater to use all suggestions.
Supported optional features
search_api_autocomplete
Introduced by module: search_api_autocomplete
Lets you add autocompletion capabilities to search forms on the site. (See
also "Hidden variables" below for backend-specific customization.)
NOTE: Due to internal database restrictions, this will perform significantly
better if only a single field is used for autocompletion.search_api_facets
Introduced by module: search_api_facetapi
Allows you to create facetted searches for dynamically filtering search
results.
If you feel some service option is missing, or have other ideas for improving
this implementation, please file a feature request in the project's issue queue.
Known problems
Using facets with a database server will only work if the database user
Backdrop is using has the "CREATE TEMPORARY TABLES" permission.
Developer information
Database queries for searches with this module are tagged with
search_api_db_search to allow easy altering. As metadata, such database
queries will have the Search API query object set as search_api_query, and the
field settings of the server for the corresponding search index as
search_api_db_fields.
