DisjunctionMaxQuery may be one you are looking for. http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/DisjunctionMaxQuery.html *This is useful when searching for a word in multiple fields with different boost factors (so that the fields cannot be combined equivalently into a single search field). We want the primary score to be the one associated with the highest boost, not the sum of the field scores (as BooleanQuery would give)*
