org.apache.lucene.index.memory.MemoryIndex.search()
Convenience method that efficiently returns the relevance score by matching this index against the given Lucene query expression. @param query an arbitrary Lucene query to run against this index @return the relevance score of the matchmaking; A number in the range[0.0 .. 1.0], with 0.0 indicating no match. The higher the number the better the match.
