Inner workings

The NodeIndexingManager listens to signals emitted from Neos Content Repository and the PersistenceManager if realtimeIndexing.enabled is true (which it defaults to).

• nodeAdded, nodeUpdated, afterNodePublishing trigger indexNode()
• nodeRemoved triggers removeNode()
• allObjectsPersisted triggers flushQueues

During a single request the queue with index changes is only flushed once the indexingBatchSize has been reached (see flushQueuesIfNeeded()).

In case the operation queues are flushed, the IndexingManager in turn uses the NodeIndexer to run indexNode() and removeNode() respectively.

If realtimeIndexing.enabled is false, the node index is only updated when built manually.
