And as anyone who's spent any time searching this site knows, there's gold in them thar old topics!

That's why it's important to remember to use the site's google search box as well as the standard box. The google box will search and find older stuff as well as newer entries. But the wild card search parameters "*" doesn't work for numbers (this is a google shortcoming probably done to prevent their servers from bogging down searching for all occurences of jpt4* in an alpha string then billions of results if included in a numerical or alpha numerical string)

The main Appliantolgy search box will respect the wild card "*" for alpha-numerical searches but the searches are limited to entries made in the last year or so.
