I hardcoded my default to equal my (current) max of 4 years. I was getting annoyed that it would show no results when I'd forget to change the "Date Range" (which was often). :/
My board's been around over 5 years, however, and I'd like an option to have it search everything without having to change it. Since I don't allow guests to search at the moment, and I only get a handful of logged in users at one time (up to 25 lately), I think I'm gonna up that to 6 years and see how it goes...
