/**
* Interface IFullTextSearchPlatform
*
* This interface must be use when creating a Search Platform for FullTextSearch.
*
* A Search Platform is an extension to the FullTextSearch that will act as a
* a gateway between FullTextSearch and a search server (ie. ElasticSearch,
* Solr, ...)
*
* Multiple Search Platform can exist at the same time in Nextcloud, however only
* one Search Platform will be used by FullTextSearch.
* Administrator must select at least one Search Platform to be used by
* FullTextSearch in the admin settings page.
*
* The content provided by FullTextSearch comes in chunk from multiple Content
* Provider. Each chunk is identified by the ID of the Content Provider, and the
* ID of the document.
*
*
* To oversimplify the mechanism:
*
* - When indexing, FullTextSearch will send providerId, documentId, content.
* - When searching within the content of a Content Provider, identified by its
* providerId, FullTextSearch expect documentId as result.
*
*
* The Search Platform ia a PHP class that implement this interface and is defined
* in appinfo/info.xml of the app that contains that class:
*
* <fulltextsearch>
* <platform>OCA\YourApp\YourSearchPlatform</platform>
* </fulltextsearch>
*
* Multiple Search Platform can be defined in a single app.
*
* @since 15.0.0
