The issue where the document count does not increase while the Azure Search indexer displays "In Progress" can be attributed to transient errors. These errors occur when an indexer execution is already in progress, and a new indexer run is initiated. Common causes include transient network communication interruptions, timeouts from long-running processes, or specific document nuances. These errors are temporary and should resolve in subsequent indexer runs. It is advisable to schedule your indexer to handle these errors effectively. In such cases, recreating the indexer has resolved the issue. For more details on handling transient errors, refer to this documentation: Common errors and warnings in Azure AI Search.
