Class FieldComparer.RelevanceComparer

Sorts by descending relevance. NOTE: if you are sorting only by descending relevance and then secondarily by ascending docID, performance is faster using TopScoreDocCollector directly (which all overloads of Search(Query, Int32) use when no Sort is specified).
