$smwgFulltextDeferredUpdate is a configuration parameter that sets the number of expected updates for the index table of the full-text search thus allowing to throttle it. It was introduced in Semantic MediaWiki 2.5.0.1

It can be of advantage to postpone the index update using a deferred job execution to decouple changes to the storage back-end and the full-text index table. In case this configuration setting and the $smwgEnabledDeferredUpdate configuration parameter are both set to "true", i.e. enabled then the updater will try to open a new process for posting instructions to execute the "SearchTableUpdateJob" immediately otherwise it will be added to the job queue and MediaWiki's "runJobs.php" maintenance script is required to perform it.

If a user wants to avoid the job queue being used for performing updates via "SearchTableUpdateJob" then this setting can be disabled by changing the setting to "false".

The "rebuildFulltextSearchTable.php" maintenance script has to be run after changing the setting of this configuration parameter.

This setting only takes effect if the full-text search feature was enabled.
