From 0ed3beb875b46caaf9a8ce1d629f9c2c7185bc7f Mon Sep 17 00:00:00 2001
From: john <john>
Date: Tue, 26 Nov 2002 18:31:52 +0000
Subject: [PATCH] making search more comprehensible by associating the
 (potentially weird or potentially fairly intuitive) indexing logic for each

 searching and result displaying.

also probably useful in future configuration schemes.....
