RAG0004: Query and retrieval of the embedded chunks (3) #6

Closed tenzin3 closed 2 weeks ago

tenzin3 commented 1 month ago

Description:

Querying the vector database with a given user input and retrieving the top-k chunks. The number of chunks to be retrieved depends on the chunking method and is subject to change. If the majority of the retrieved chunks are not relevant, an additional reranker model needs to be added.

Excepted Output:

A number of relevant text chunks that will be forwarded to the prompt template of the LLM.
