FacetWP Schedule Indexer

FacetWP Schedule Indexer is an official FacetWP extension designed to automate the content reindexing process on WordPress sites via WP-Cron. It is intended for projects with large volumes of data —directories, online stores, job portals, or any site with thousands of filterable entries— where keeping the facet index manually updated becomes a tedious and error-prone task.

The plugin creates a WP-Cron event that triggers a full reindex of the FacetWP index periodically. By default, indexing runs every hour, but the administrator can configure custom intervals based on the site's needs. This ensures that filters and search results always show up-to-date information, even when content changes outside the normal WordPress editing flow, such as with bulk imports, stock updates, or external synchronizations.

Key features include the ability to choose between built-in schedules (hourly, twice daily, daily, or weekly) or create custom schedules via the facetwp_index_schedule hook. It also allows disabling individual automatic indexing to prevent multiple indexing processes from running simultaneously, thus optimizing server performance. To verify proper operation, the plugin offers indexer statistics showing the last time the process ran.

This add-on is especially valuable for sites that regularly import or update large amounts of content, as it eliminates the need for constant manual intervention. Additionally, it is compatible with WP-CLI and can be integrated with server cron for more reliable scheduling, independent of site traffic. For developers, it offers customization hooks that allow adjusting the indexer's behavior to specific needs.

In summary, FacetWP Schedule Indexer is the ideal solution for administrators and developers managing WordPress sites with FacetWP who need to keep their facets always accurate without dedicating time to manual reindexing processes.
