Detailed Description

Constructs a query selecting all terms greater than lowerTerm but less than upperTerm.

There must be at least one term and either term may be null, in which case there is no bound on that side, but if there are two terms, both terms must be for the same field.

Member Function Documentation

const TCHAR* lucene::search::RangeQuery::getQueryName ( ) const [virtual]

Implements lucene::search::Query.

static const TCHAR* lucene::search::RangeQuery::getClassName ( ) [static]

Query* lucene::search::RangeQuery::rewrite ( lucene::index::IndexReader * reader ) [virtual]

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

Reimplemented from lucene::search::Query.

Query* lucene::search::RangeQuery::combine ( Query ** queries ) [virtual]

Expert: called when re-writing queries under MultiSearcher.

Only implemented by derived queries, with no _createWeight(Searcher) implementatation.

Reimplemented from lucene::search::Query.

TCHAR* lucene::search::RangeQuery::toString ( const TCHAR * field ) const [virtual]

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

The representation used is one that is supposed to be readable by QueryParser. However, there are the following limitations:

If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.

Implements lucene::search::Query.

Query* lucene::search::RangeQuery::clone ( ) const [virtual]

Returns a clone of this query.

Implements lucene::search::Query.

bool lucene::search::RangeQuery::equals ( Query * other ) const [virtual]
