Erick Erickson reopened LUCENE-2518:
------------------------------------
> Make check of BooleanClause.Occur[] in MultiFieldQueryParser.parse less
> stubborn
> --------------------------------------------------------------------------------
>
> Key: LUCENE-2518
> URL: https://issues.apache.org/jira/browse/LUCENE-2518
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/queryparser
> Affects Versions: 2.9, 2.9.1, 2.9.2, 2.9.3, 3.0, 3.0.1, 3.0.2
> 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.
