I can verify that bad things are going on with backslashes and the query parser in lucene 1.4.3 foo:hi\\ ==> foo:hi\ (foo:hi\\) ==> exception foo:"hi\\" ==> foo:hi\\ foo:hi\\^3 ==> foo:hi\^3 foo:"hi \\ there" ==> foo:"hi \\ there" foo:'hi there' ==> foo:'hi foo:"\"" ==> exception foo:hi\" ==> foo:hi"
So there appears to be no way to query for something with a quote and a space in the same string... IMHO, backslash should work as an escape inside quoted values. -Yonik On 8/12/05, Matt Magoffin <[EMAIL PROTECTED]> wrote: > The strings are not coming from Java literals, actually, so I didn't think > that was the problem. > > Any other thoughts? > > -- m@ > > > I think you are encountering a "double escape" problem in java literals. > > QP is seeing a backslash in front of the ) and waiting for you to finish > > the paren grouping. > > > > how are you passing that string to the QP, is it embedded in your java > > code? if so the java compiler is interpreting your \\ and your java app > > is never seeing it. > > > > : Date: Fri, 12 Aug 2005 07:30:19 -0700 (PDT) > > : From: Matt Magoffin <[EMAIL PROTECTED]> > > : Reply-To: java-user@lucene.apache.org > > : To: java-user@lucene.apache.org > > : Subject: QueryParser exception on escaped backslash preceding ) > > character > > : > > : When I try to parse a query with an escaped backslash character like > > this > > : (using Lucene 1.4.3): > > : > > : -id:20677 +(addr:Street143 AND zip:\\) > > : > > : the QueryParser thows an Exception: > > : > > : Encountered "<EOF>" at line 1, column 289. > > : Was expecting one of: <AND> ... <OR> ... > > : <NOT> ...
