Context

Our first implementation is too simple for realistic use cases.  We wanted to make something simple to adopt so that new LangChain users wouldn't be dissuaded but users of Hybrid today need complexity.

I had a conversation about the with erik.hatcher@mongodb.com who would consult on the API and best practices.

I am thinking that ripping out "text": {"query": query, "path": search_field} and replacing with "compound":query,  makes sense because it allows arbitrary complexity. This is the only way that I see in the docs that I can apply a filter through $search. I also don't see where to limit the results of $search. Another big issue is currently a $match after $search, and this opens up a nightmare performance scenario.
