Event-driven catalog indexing

The event-driven model for indexing the catalog ensures that changes to catalog data are automatically updated in the search index. The Indexing Processor State section is at Commerce > Settings > Catalog Indexing.

Recover and Invalidate manage the system that handles event-driven indexing.

• Recover – Rebuild the full search index. When recovery is complete, the state changes to valid and changes are automatically pushed into the index. Recover is disabled if the queue state is valid.
• Invalidate – Clean out the queue and start over. If the queue state is invalid, selecting Invalidate resets the state, and selecting Recover rebuilds the search index. If the state is recovering, the page displays a completion percentage of the recovery operation, retrieved from the search provider.

The status indicator displays the state of a queue of catalog entries that need to be reindexed. If the state is invalid, the system cannot distinguish between actual catalog data and the search index.

When the state is valid again, the handler displays the number of items in the queue — that is, the number of catalog entries that need to be indexed. This number can grow after a catalog import because changed catalog entries are reindexed in the background. In most cases, the number is small.
