org.apache.lucene.search.BooleanFilter
A container Filter that allows Boolean composition of Filters. Filters are allocated into one of three logical constructs; SHOULD, MUST NOT, MUST The results Filter BitSet is constructed as follows: SHOULD Filters are OR'd together The resulting Filter is NOT'd with the NOT Filters The resulting Filter is AND'd with the MUST Filters
