Examples of org.apache.lucene.search.Searcher.search()

org.apache.lucene.search.Searcher.search()
Search implementation with arbitrary sorting. Finds the top n hits for query, applying filter if non-null, and sorting the hits by the criteria in sort.
NOTE: this does not compute scores by default; use {@link IndexSearcher#setDefaultFieldSortScoring} toenable scoring. @throws BooleanQuery.TooManyClauses
