Hi Erik I think the best solutuion is to have a NullAnalayzer class that allows a simple pass through
The query parser then can be passed with a PerFieldAnalayzer that knows when to select NullAnalayzer or some other based on the Field:"data... " Field2:"pp" format this is something that the query parser is already geared up to do regards Rupinder >-----Original Message----- >From: Erik Hatcher [mailto:[EMAIL PROTECTED] >Sent: 20 October 2004 16:29 >To: Lucene Users List >Subject: Re: Null or no analyzer > > > >On Oct 20, 2004, at 9:55 AM, Aviran wrote: >> AFIK if the term "Election 2004" will be between quotation marks this >> should >> work fine. > >No, it won't.
