Thanks, mouser. One other thing: I was trying to get the exclude subdirectories feature to work and couldn't seem to make it do anything. I was particularly interested in preventing the search from recursing .svn subdirectories, but nothing I put in seemed to work. (e.g. all .svn directories have an "entries" file. I tried the following strings in the "Exclude subdirectories whose full path..." field, without success: "svn", ".svn", "\.svn\", and ".svn\", in an attempt to prevent the "entries" file from showing in the results list. However, this does work: "\.svn".
This is an issue I was about to ask about a while back because I thought it didn't work, but then found a way. Now, I'm wondering if it's related in any way, and thought it might be useful to you (as info) or to others (in case they can't get it to work).
