Copilot Agent not retrieving data from Azure AI Search

Question

Hi, I am trying to use Azure AI search as a knowledge source for my Copilot Agent in Copilot Studio. I have successfully connected my AI Search resource using the endpoint and API Key. The index is found correctly with the number of documents and the size. The knowledge table also shows that it is ready.

However, when I am testing the agent, whatever question I ask, the response from the activity map is 'No results found'.

I need help with this

Hi Neelamraju, Sashank ,

Azure AI Search is set up as a knowledge source for the Copilot Agent in Copilot Studio. The connection looks fine — the index name, document count, and size are all showing correctly. The knowledge table also shows “Ready”. But during testing, any question asked returns "No results found" in the activity map.

Here’s what I’ve verified so far:

1. The index in Azure contains documents with data (confirmed using * in Search Explorer).
2. The correct field holding the main content is selected in Copilot Studio.
3. The documents are [PDF/Word/JSON – insert your type], and an indexer with a skillset has been used to extract the content if needed.
4. No filters (like language or tags) are applied in Copilot Studio that could block documents.
5. The same questions return expected results when tested directly in Azure Search Explorer.

Thanks,
