> There are some use-cases where it'd be nice if the "terms" qparser created a query that could be run as a postfilter.  Particularly, when users are checking for hundreds or thousands of terms, a postfilter implementation can be more performant than the standard processing.
> WIth this issue, I'd like to propose a post-filter implementation for the {{docValuesTermsFilter}} "method".  Postfilter creation can use a SortedSetDocValues object to populate a DV bitset with the "terms" being checked for.  Each document run through the post-filter can look at their doc-values for the field in question and check them efficiently against the constructed bitset.
