Can Agent Builder use multiple vector stores per Agent?

API
1

I’m using Agent Builder and am having issues with file search. I would like to add more than 1 vector store file search to an agent. Is there a way to accomplish this?

Thanks in advance!

Welcome to the community @spoon239.

This is a bit confusing.

The API supports vector_store_ids, so multiple vector stores are supported there. The Agent Builder File Search node is less clear, and I haven't seen documentation that explicitly confirms support for searching across multiple stores.

I've tried adding multiple vector stores, but it only seems to reference the first one uploaded, so it might be a current limitation in Agent Builder.

For now, the most reliable workaround is to combine the files into a single vector store, or use separate File Search/agent nodes if you need to keep the sources isolated.

Curious if anyone has found a cleaner routing setup for this.
