interface SearchIndexingInterface in Drupal 9
Same name and namespace in other branches
- 8 core/modules/search/src/Plugin/SearchIndexingInterface.php \Drupal\search\Plugin\SearchIndexingInterface
Defines an optional interface for SearchPlugin objects using an index.
Plugins implementing this interface will have these methods invoked during search_cron() and via the search module administration form. Plugins not implementing this interface are assumed to be using their own methods for searching, not involving separate index tables.
The user interface for managing search pages displays the indexing status for search pages implementing this interface. It also allows users to configure default settings for indexing, and refers to the "default search index". If your search page plugin uses its own indexing mechanism instead of the default search index, or overrides the default indexing settings, you should make this clear on the settings page or other documentation for your plugin.
Multiple search pages can be created for each search plugin, so you will need to choose whether these search pages should share an index (in which case they must not use any search page-specific configuration while indexing) or they will have separate indexes (which will use additional server resources).

/**
* Updates the search index for this plugin.
*
* This method is called every cron run if the plugin has been set as
* an active search module on the Search settings page
* (admin/config/search/pages). It allows your module to add items to the
* built-in search index by calling the index() method on the search.index
* service class, or to add them to your module's own indexing mechanism.
*
* When implementing this method, your module should index content items that
* were modified or added since the last run. There is a time limit for cron,
* so it is advisable to limit how many items you index per run using
* config('search.settings')->get('index.cron_limit') or with your own
* setting. And since the cron run could time out and abort in the middle of
* your run, you should update any needed internal bookkeeping on when items
* have last been indexed as you go rather than waiting to the end of
* indexing.
