Class BKDPointInBBoxQuery

java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.bkdtree.BKDPointInBBoxQuery

All Implemented Interfaces:

Cloneable

public class BKDPointInBBoxQuery
extends Query

Finds all previously indexed points that fall within the specified boundings box.

The field must be indexed with BKDTreeDocValuesFormat, and BKDPointField added per document.

NOTE: for fastest performance, this allocates FixedBitSet(maxDoc) for each segment. The score of each hit is the query boost.

BKDPointInBBoxQuery

public BKDPointInBBoxQuery(String field,
                   double minLat,
                   double maxLat,
                   double minLon,
                   double maxLon)

Matches all points >= minLon, minLat (inclusive) and < maxLon, maxLat (exclusive).

Method Detail

createWeight

public Weight createWeight(IndexSearcher searcher,
                  boolean needsScores)
                    throws IOException

Description copied from class: Query

Expert: Constructs an appropriate Weight implementation for this query.

Only implemented by primitive queries, which re-write to themselves.

Overrides:

createWeight in class Query

needsScores - True if document scores (Scorer.score()) or match frequencies (Scorer.freq()) are needed.

Throws:

IOException

rewrite

public Query rewrite(IndexReader reader)
              throws IOException

Description copied from class: Query

Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.

Overrides:

rewrite in class Query

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class Query

equals

public boolean equals(Object other)

Overrides:

equals in class Query

toString

public String toString(String field)

Description copied from class: Query

Prints a query to a string, with field assumed to be the default field and omitted.

Specified by:
