> If a query uses both indexed and non-indexed fields we should be able to execute it in two phases. A first less selective query on the index and then post process it by reapplying the whole filter again to results of the first phase.
> This should be more efficient than completely ignoring the indexed fields and executing the non-indexed query on the whole data set.
> A possible idea to derive the query to be executed in first phase is to apply the Boole-Shannon expansion theorem ([http://en.wikipedia.org/wiki/Boole%27s_expansion_theorem]).
