# Same question, two tenants

shop-a asks "How do I reset my account password?"  -> model call (calls so far: 1)
shop-b asks the identical question -> model call, no hit (model calls so far: 2)
shop-a asks again               -> cache hit
entries in the index: 2 (one per tenant)
The filter is a tag on the document and an expression on the search: tenant == 'shop-b'.
nearest(shop-a, q) without asking as shop-b still finds: "How do I reset my account password?"
