Context

The $search query should be more flexible. Our default may be ok, but one should be able to override it with something arbitrarily flexible. (e.g. a compound filter with text wildcard star).

We do this sort of open-ended style in post-filter.
 

    pipeline = [
        {
            "$search": {
                "index": index_name,
                "text": {"query": query, "path": search_field},  
            }
        }
    ]
