Field QUERY_FIRST_FILTER_STRATEGY

A filter strategy that advances the Query or rather its Scorer first and consults the filter DocIdSet for each matched document.

Note: this strategy requires a Bits to return a non-null value. Otherwise this strategy falls back to LEAP_FROG_QUERY_FIRST_STRATEGY

Use this strategy if the filter computation is more expensive than document scoring or if the filter has a linear running time to compute the next matching doc like exact geo distances.
