your are right its QueryParser throw the exception. I think I got the point. QueryParser doesn't allows asterisk at the begining but SerchIndexer (could) work.
For a example when I quering "\**TI" it returned me machings "J400-C-V-S10-T1" and "J400-C-V-S8-T1". -----Original Message----- From: Erik Hatcher [mailto:[EMAIL PROTECTED] Sent: Wednesday, 27 July 2005 10:35 AM To: java-user@lucene.apache.org Subject: Re: Analyzer or QueryParser problem?

I'm guessing QueryParser actually throws an exception, not IndexSearcher, correct? Wildcards at the beginning of a term are not allowed by QueryParser. Using \**11 works because the first character is literally an asterisk, and thus is a legal expression. > I couldn't find any documentation related to this.

Interesting hack!
