Make check of BooleanClause.Occur[] in MultiFieldQueryParser.parse less stubborn
--------------------------------------------------------------------------------
Key: LUCENE-2518
URL: https://issues.apache.org/jira/browse/LUCENE-2518
Project: Lucene - Java
Issue Type: Improvement
Components: QueryParser
Affects Versions: 3.0.2, 3.0.1, 3.0, 2.9.3, 2.9.2, 2.9.1, 2.9
Reporter: Itamar Syn-Hershko
Priority: Minor
Update the check in:
public static Query parse(Version matchVersion, String query, String[] fields,
BooleanClause.Occur[] flags, Analyzer analyzer) throws ParseException {
if (fields.length != flags.length)
throw new IllegalArgumentException("fields.length != flags.length");
To be:
if (fields.length > flags.length)
So the consumer can use one Occur array and apply fields selectively. The only
danger here is with hitting a non-existent cell in flags, and this check will
provide this just as well without limiting usability for such cases.
