Is your feature request related to a problem? Please describe.

Under the scenario of multi-tenant, sometimes it is meaningless to search across tenants, i.e., search for TopK nearest vectors while satisfying userID in [123, 456, 789]. It is sufficient to search with expression userID == 123 or userID==123 && location == 'Earth'.

Describe the solution you'd like.

We could build/load/search part of the indices to

• reduce build time
• reduce load time
• reduce memory usage

Describe an alternate solution.
