Troubleshooting 

No answers from indexed content 

Check:

  • the assistant profile test under AI Assistant > Diagnostics succeeds;
  • indexer has written documents;
  • retriever uses the same vector store connection and collection as the indexer;
  • the measured embedding dimension matches the AI connection configuration;
  • max_retrieval_results is greater than zero;
  • score threshold is not too strict.

Duplicate retrieval results 

Check:

  • stable source identifiers;
  • source hash generation;
  • collection and vector store connection scoping;
  • whether old collection data must be rebuilt after indexing changes.

Wrong or missing sources 

Check:

  • metadata is present in vector payload;
  • prompt_metadata_fields includes relevant fields;
  • prompt_metadata_fields includes title and URL;
  • answer generator prompt asks for source-aware answers if needed.

Query optimizer answers instead of rewriting 

Check that the query optimizer step prompt says it must return only a search query and must not answer or summarize the retrieved result.
