Hi, lucene raises a notice if the following invalid query is supplied to the parser: dgdsdsg#+ü\
This happens in the QueryLexer on line 477 (addLexemeChar) where an element of $this->_queryString is accessed with $this->_queryStringPosition as key without checking if that key is a valid index. best regards, Stefan Oestreicher -- Dr. Maté GmbH Stefan Oestreicher / Entwicklung [EMAIL PROTECTED] http://www.netdoktor.at Tel Buero: + 43 1 405 55 75 24 Fax Buero: + 43 1 405 55 75 55 Alser Str. 4 1090 Wien Altes AKH Hof 1 1.6.6
