dify - 💡(How to fix) Fix Retrieval Test return the "null" [3 comments, 2 participants]

TL;DR

Adjusting the retrieval strategy parameters, such as weighting or TopK/Score threshold, may not be sufficient to retrieve the segment containing "修改教材", and a more detailed examination of the knowledge base and retrieval algorithm is needed.

Guidance

• Verify that the segment containing "修改教材" is correctly indexed and stored in the knowledge base.
• Check the character encoding and formatting of the segment to ensure it matches the expected format.
• Review the retrieval algorithm to ensure it is correctly handling non-English characters and phrases.
• Consider testing the retrieval with a simplified query or a different retrieval strategy to isolate the issue.

Notes

The issue may be related to the handling of non-English characters or the specific retrieval strategy used. Further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Try using a different retrieval strategy or adjusting the query to see if the segment can be retrieved. This may help isolate the issue and provide more information for further debugging.
