com.flaptor.hounder.searcher.filter.BooleanFilter
Implement a Filter that is the rusult of ANDing a series of filters. This class is "immutable", but only after the first use of getLuceneFilter. This class is not thread safe. This filter is not cached on it's own, but the filters passed to it may be cached. There would be little gain in caching this class, as it does't generate a lucene filter with it's associated lengthy bitArray.
