as of 2.1, as I remember, you can use leading wildcards but ONLY you set a flag (see setAllowLeadingWildcard in QueryParser). Be aware of the TooManyClauses issue though (search the mail archive and you'll find many discussions of this issue).

Sachin, Thanks for quick response. Is there any code example i can take look? I'm not familiar with the technique you mentioned. My question is how the analyzer knows "buss" is not a plural and bears is a plural. Lucene supports wildcard. However, we can not use wildcard at the beginning of search term such as *bear. is there a way to match *bear* (bear, bears, forbearance etc.) by search tern "bear"? thanks >From: "Kainth, Sachin" <[EMAIL PROTECTED]> >Reply-To: java-user@lucene.apache.org >To: <java-user@lucene.apache.org> >Subject: RE: Plural word search >Date: Thu, 8 Mar 2007 17:14:02 -0000 > >Hi Tony, > >Lucene certainly does support it.
