Oliver Becker created LUCENE-6703:
-------------------------------------
Summary: IllegalArgumentException in QueryParserBase.parse()
Key: LUCENE-6703
URL: https://issues.apache.org/jira/browse/LUCENE-6703
Project: Lucene - Core
Issue Type: Bug
Components: core/queryparser
Affects Versions: 4.10.4
Reporter: Oliver Becker
I have encountered a very special case where parsing a certain String with the
{{MultiFieldQueryParser}} causes an {{IllegalArgumentException}} thrown in the
constructor of {{org.apache.lucene.util.automaton.RegExp}}. I would have
expected a {{ParseException}} instead (as stated in the API doc).
{code}
QueryParser parser = new MultiFieldQueryParser(...);
parser.parse("/x)/");
{code}
The "evil" search string is *{{/x)/}}*.
