It appears that you can no longer use anything but the "search" field in the "Query view" text box. Previously the Query view allowed you to have a query string type syntax. For example: search={search criteria}&searchMode=all&select={fields}&filter={filters}&count=true&orderby={order by}
I found this by switching to the JSON view and saw that the configuration looked different. 1) It was stuffing my entire query into the "search" field and 2) adding some extra fields as well.
After converting my http query into JSON and using the JSON view, I got the expected results!
