Hi @homer_thompson , there are a couple of ways. If you know the _id list ahead of time you could randomly sample a document and then use that to search with. Alternatively, we have a context_vector that can be used for a random search. In this case, you would create a random vector and then search directly with that.
Here is an example;
res = client.search({query:0.0}, context={"tensor":[{"vector": context_vector, "weight": 1.0}]})
