Examples of ScoredDocIDsIterator

org.apache.lucene.facet.old.ScoredDocIDsIterator
Iterator over document IDs and their scores. Each {@link #next()} retrievesthe next docID and its score which can be later be retrieved by {@link #getDocID()} and {@link #getScore()}. NOTE: you must call {@link #next()} before {@link #getDocID()} and/or {@link #getScore()}, or otherwise the returned values are unexpected. @lucene.experimental
