Is your feature request related to a problem?
We need to find chunks that are similar to another chunk. That would be an easy vector search operation, since the embedding vector of the first chunk is already in RAGFlow's database, but there is no API for that kind of retrieval and as such you need to send the text representation of the chunk and it will run through the embedding process, which is slow and incurs unnecessary API costs.
Describe the feature you'd like
A simple API method to retrieve chunks that are similar to other chunks of the same document. With the same similarity parameter as the retrieve() method.
Describe implementation you've considered
Using the text of the chunk as a query.
Documentation, adoption, use case
Finding similar products to a given product.
