doSetNextReader
protected void doSetNextReader(LeafReaderContext context) throws java.io.IOException
Description copied from class:SimpleCollector
This method is called before collectingcontext
.- Overrides:

in classSimpleCollector
- Throws:
java.io.IOException

collect
public void collect(int doc)
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
IndexSearcher.doc(int)
orIndexReader.document(int)
on every hit. Doing so can slow searches by an order of magnitude or more.- Specified by:
