I feel like this is an essential feature you guys need to implement. I want to be able to get similar documents to an array of ids. It's currently fine with one, but it's really a feature I feel would be greatly appreciated from the community. This workaround will work for my use case but I need to capture the product_name in the user sessions now as well instead of just the id which is much much much more reliable. A product_name is dynamic and can change.
