Class Scorer
Expert: Common scoring functionality for different types of queries.
A Scorer iterates over documents matching a
query in increasing order of doc Id.
Document scores are computed using a given Similarity
implementation.
NOTE: The values Float.Nan, Float.NEGATIVE_INFINITY and Float.POSITIVE_INFINITY are not valid scores. Certain collectors (eg TopScoreDocCollector ) will not properly collect hits with these scores.
