setWeight
public void setWeight(Weight weight)
Description copied from interface:Collector
Set theWeight
that will be used to produce scorers that will feedLeafCollector
s. This is typically useful to have access toWeight.count(org.apache.lucene.index.LeafReaderContext)

collect
public void collect(int doc) throws java.io.IOException
Description copied from interface:LeafCollector
Called once for every document matching a query, with the unbased document number.Note: The collection of the current segment can be terminated by throwing a
CollectionTerminatedException
. In this case, the last docs of the currentLeafReaderContext
will be skipped andIndexSearcher
will swallow the exception and continue collection with the next leaf.Note: This is called in an inner search loop. For good search performance, implementations of this method should not call
StoredFields.document(int)
on every hit. Doing so can slow searches by an order of magnitude or more.- Specified by:
