There are some issues with RAG full-text search

[lai-serena]

I used xinreference to integrate the BGE or BCE embedding model and added some knowledge to the knowledge base. Both vector search and hybrid search yielded results, but full-text search yielded no search results. Why is this?
This is data in the knowledge base and there is a "黑名单"

But when using full-text search, there were no results

It depends how you search for the text. All 3 options work a little bit differently from each other and the result depends on input search.

Thank you for your answer. But I am really confused about what kind of input will result in full-text search. Does this mean that the input should have more details and text?

Well, this might help you out https://docs.dify.ai/features/retrieval-augment/hybrid-search#full-text-search

Can't read your language so I don't even know how the chunk looks and what you are looking for.

yes, when I use Chinese character , most full text search return none records .
