Why Does Haystack Stop Grouping Related Chunks After Adding Metadata?

[prashant-qualwebs]

Need help!
I am using Haystack for retrieving relevant chunks from documents. When a user sends a query, the system returns the top 3 most relevant chunks from the complete document.

Now, I have added some metadata to the documents. For example, each section belongs to a specific chunk_id and index_id. After adding this metadata, when I run the same query again, the system only returns results at the section level.

Previously, the response could include multiple related parts together (for example, two sections combined in one answer). But now, it does not return those related parts together anymore—it only returns individual section-wise results.

Does anyone have an idea where I might be making a mistake? Or is this expected behavior? Is it possible to get combined results again?
