A {@link Collector} implementation that collects the top-scoring hits, returning them as a {@link TopDocs}. This is used by {@link IndexSearcher} to implement {@link TopDocs}-based search. Hits are sorted by score descending and then (when the scores are tied) docID ascending. When you create an instance of this collector you should know in advance whether documents are going to be collected in doc Id order or not.

NOTE: The values {@link Float#NaN} and {Float#NEGATIVE_INFINITY} are not valid scores. This collector will not properly collect hits with such scores.
