Handle multi-vector in exact search scenario

[heemin32]

Description

When filter query is provided using Faiss engine, knn search can be run in exact search mode instead of ANN mode based on few conditions. One of the condition is when k is larger than the size of list of filtered IDs.

Added some comments related to the new interface classes which we have created. I think we can do quite a lot better there. Let's see if we really need the interface and those extra functions.
