Examples of org.apache.lucene.search.DocIdSetIterator.nextDoc()

org.apache.lucene.search.DocIdSetIterator.nextDoc()
Advances to the next document in the set and returns the doc it is currently on, or {@link #NO_MORE_DOCS} if there are no more docs in theset.
NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior. @since 2.9
