Re: Query: A ? B
Actually a slop of 1 does guarantee order... it is either an exact match or 1 term off. It takes a slop of 2 or greater for reverse order matches. But it is not exactly 1 term off, which is what Jochen wants. *shrug* Erik On Mar 4, 2004, at 6:22 PM, Otis Gospodnetic wrote: Ah, sorry, I had misread your email, thinking you were asking a way to match a single character.

Re: Query: A ? B
Right Otis was confused by what you were asking. Google supports what you are asking for, I believe, although I don't recall if an '*' indicates one or more or just one. As far as I know, there is no easy way to do the exact distance like you desire. You could always clone the PhraseQuery stuff into a custom Query that uses an == instead of a for the slop. Although you'll also need to tweak this to disallow reversing of terms too. Slop handles terms out of order too. Maybe the new span feature can do this?

RE: Query: A ? B
I think I know my way around the Span feature reasonably well ... and I don't think it can be used for what I want to do. But I would love to be proven wrong on this one. :) -Original Message- From: Erik Hatcher [mailto:[EMAIL PROTECTED] Sent: Thursday, March 04, 2004 1:52 PM To: Lucene Users List Subject: Re: Query: A ?

RE: Query: A ? B
Ah, sorry, I had misread your email, thinking you were asking a way to match a single character. The only thing that comes to my tired mind now is a phrase query with a slop of 1, but that doesn't gurantee order, I believe.
