Weaviate is probably the easiest choice if your core requirement is: "Given a query, find documents that match exact terms and understand meaning."
ChatGPT Search ChatGPT Search
Weaviate is probably the strongest "drop in and build" option today for hybrid search because it treats keyword and vector retrieval as a single search operation.

We need to handle complex, hierarchical user permissions in our semantic search. Which vector database has the best support for advanced metadata filtering and ACLs?88%

Weaviate is worth testing first because its filtering architecture is designed around making metadata constraints participate in retrieval rather than merely removing results afterward.
ChatGPT Search ChatGPT Search
Weaviate is particularly interesting if your hierarchy is primarily tenant → collection → objects.
