Method Detail

rewrite

public Query rewrite(Query original)
              throws java.io.IOException

Description copied from class: IndexSearcher

Expert: called to re-write queries into primitive queries.

termStatistics

public TermStatistics termStatistics(Term term,
                                     TermContext context)
                              throws java.io.IOException

Description copied from class: IndexSearcher

Returns TermStatistics for a term. This can be overridden for example, to return a term's statistics across a distributed collection.

Overrides:

termStatistics in class IndexSearcher

Throws:

java.io.IOException

collectionStatistics

public CollectionStatistics collectionStatistics(java.lang.String field)
                                          throws java.io.IOException

Description copied from class: IndexSearcher

Returns CollectionStatistics for a field. This can be overridden for example, to return a field's statistics across a distributed collection.

Overrides:

collectionStatistics in class IndexSearcher

Throws:

java.io.IOException

search

public TopDocs search(Query query,
                      int numHits)
               throws java.io.IOException

Description copied from class: IndexSearcher

Finds the top n hits for query.

Overrides:

search in class IndexSearcher

Throws:

java.io.IOException

                    throws java.io.IOException

Description copied from class: IndexSearcher

Finds the top n hits for query where all results are after a previous result (after).

By passing the bottom result from a previous page as after, this method can be used for efficient 'deep-paging' across potentially large result sets.

Overrides:

searchAfter in class IndexSearcher

Throws:

java.io.IOException

localSearchAfter

public TopDocs localSearchAfter(ScoreDoc after,
                                Query query,
