URGENT: Filtering Retrieval Search in Weaviate Based on Tenant-Specific Uploaded Files

Hi @AmanAda,
I am not an expert in langchain, but I can speak from a Weaviate level.

Overall, you don’t need to configure Weaviate in any special way. You only need a property with a file_name (or some other identificator), and you can filter using contains_any.

Get the tenant

First, as part of your query, you need to specify the tenant you are searching on. With the Python client, this looks like this:

my_collection = client.collections.get("MyCollectionName")

# Get the specific tenant's version of the collection
my_tenant = my_collection.with_tenant("tenant_name")

See more here.

Filter (contains_any) on files

Then, you need to run a query on the tenant with a filter using contains_any, which should contain all the files you want to search on. Here is an example with a Weaviate Python client:

import weaviate.classes as wvc

response = my_tenant.query.near_text(
    query="search term here",
    filters=wvc.Filter("file_name").contains_any(["file1", "file2", "file3"]),
    limit=4
)
