static boolean	Filters.shouldUseBitmapIndex(Filter filter, BitmapIndexSelector indexSelector, FilterTuning filterTuning) This method provides a "standard" implementation of Filter.shouldUseBitmapIndex(BitmapIndexSelector) which takes a Filter, a BitmapIndexSelector, and FilterTuning to determine if: a) the filter supports bitmap indexes for all required columns b) the filter tuning specifies that it should use the index c) the cardinality of the column is above the minimum threshold and below the maximum threshold to use the index If all these things are true, QueryableIndexStorageAdapter will utilize the indexes.
