> The standard query parser uses the default query operator for query clauses that are
created from tokenization in the query parser instead of the actual operator for the source
term.
> here is an example:
> {code}
> StandardQueryParser parser = new StandardQueryParser(new StandardAnalyzer(Version.LUCENE_34));
> parser.setDefaultOperator(Operator.OR);
> System.out.println(((BooleanQuery)parser.parse("_deleted:true AND title:東京", "f")));
> {code}
> this should yield:
> +_deleted:true +(title:東 title:京)
> as our former core query parser does but actually yields:
> +_deleted:true title:東 title:京
> seems like a bug to me, looking at the tests seems we don't test for this kind of queries
in the standard query parser tests too.
