The nullanalyzer overrides the isTokenChar method to simply return true in the tokenizer class (http://issues.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1703655).
The situation is that it seems lucene does not expect you to escape characters that exist inside of a quoted string. So my search [ authorkeyword:"MariaMy*" ] works, but [ authorkeyword:"MariaMy\*" ] does not, even though the * character should be escaped (http://jakarta.apache.org/lucene/docs/queryparsersyntax.html#Terms) So, if this is true, then the rule might be, reserved characters must be escaped EXCEPT when they are within double quotes as a phrase. When double quotes are needed within a phrase, they should be escaped with a ...... ? -----Original Message----- From: Erik Hatcher [mailto:[EMAIL PROTECTED] Sent: Thursday, October 28, 2004 3:05 PM To: Lucene Users List Subject: Re: Searching for a phrase that contains quote character On Oct 28, 2004, at 2:02 PM, Will Allen wrote: > I am using a NullAnalyzer for this field. Which means that each field is added exactly as-is as a single term? Then trying the PhraseQuery directly is a good first step - if you can get that to work then you can move on to making QueryParser work with escaping. But don't complicate things with QueryParser at first. Start with the queries constructed directly first.
