-------------------------------------

This sounds like yet another filter with all the complexity/traps/problems 
associated there.

Does something about the query cache not work for you?

> Some users benefit having {{TrackingQuery}} functionality. This query would 
> wrap another query and should be able to provide the matched DocIds for the 
> wrapped query after search is run.  For example a user running a boolean 
> query {{A or B}} could wrap query {{A}} into {{TrackingQuery}} and run the 
> boolean query and check if documents that matched the boolean query matches 
> the query {{A}}.
