Hey guys! I feel like this is a really simple question but I haven't been able to find it in the docs. Does anyone know how I can filter by a specific document from my vector store (qdrant)? For context, our users want to chat with specific documents on our platform instead of searching through all of them for an answer. So we wanted to narrow down the scope of these by just filtering the results of retrival by the document's ID or filename - which we already store in qdrant. Anyone know a good way of doing this? Thank you!!
