Dean, Any chance you want to share your view code?
In regards to the query parsing, I am not sure how this will work. Right now results for each term have to be pulled down to the client and merged together. Perhaps we could add a query method to views that allow different key values to be combined. A user could query a view with a set of keys and a merge function that could define how the key values could be combined.
