In vector retrieval, tenant filtering must pass tenantId as a metadata filter into the query before the similarity search is executed, so that the database computes distances only within the subset of vectors belonging to that tenant, rather than retrieving first and filtering afterward.

UnverifiedMetadata filtering adopts a 'filter first, then retrieve' strategy, making a single vector library logically equivalent to multiple isolated sub-libraries while avoiding the complexity of a routing layer.69% similarUnverifiedThe approach of metadata pre-filtering is to first have an LLM determine user intent and extract structured filter conditions from the query, then apply these conditions as hard filters to the vector database before executing semantic similarity search.66% similarUnverifiedRow-level filters should forcibly inject WHERE conditions at the query execution layer, rather than having the application layer or prompts declare the scope themselves.57% similarUnverifiedStoring key dimensions such as plan type as filterable metadata fields allows irrelevant branches to be excluded before retrieval, which is pre-filtering in hybrid retrieval56% similar
