Adding filtering based on metadata when performing a search. This gives a better search result due to the nature of predeterministic of the filter that ANN doesn't provide.
Solution
This implementation must be pre-filtering. This means the filtering happens not after the result of ANN but during the creation of nearest neighbors candidate pool.
