log_search テーブル

MediaWiki バージョン:

≧ 1.16

log_search テーブルです (r50567 で追加されました)。 Either or both log_search and logging.log_params can be used for storing data about log events. log_search, being indexed, is used for filtering for live queries. RevisionDelete for example uses it to filter log events down to the revision ID (not just page). For example, if revisions 48 and 49 are deleted by log event 29, then there would be two rows created in log_search, with ls_field equal to 'rev_id' for both fields, ls_value equal to 48 for the first field and 49 for the second field, and ls_log_id equal to 29 for both fields. For offline use (e.g. slow analytics), log_params is enough.

The functions used for storing data in log_search are usually ManualLogEntry::setRelations() and LogPage::addRelations() .
