[Bug]: Chat retrieval issues #2362

Closed sznariOsmosis closed 1 month ago

Is there an existing issue for the same bug?

Actual behavior

The debugging discovery is currently based on the latest 4 problems in the history to retrieve, and the debugging found that the consequence of this is that sometimes the content cannot be retrieved, but when I use the latest problem to retrieve, I can get the retrieved chunk

Expected behavior

What was the purpose of using the 4 questions to search in the first place, and will this be a hidden danger? 61726023665_ pic

It's normal. The longer the query is, the lower the recall rate is.

What is the purpose of this strategy, after testing, it uses the 4 questions of the history to retrieve chunks, which is easy to cause false detections and missed detections，Because I noticed that the code defaults to a new question composed of 3 questions from the current problem and the historical question, which are concatenated by strings

It's related to multi-turn conversations. We're gona refine it soon.
