Need to tweak search algorithm

[Tvienti]

Hi all. I'm trying to implement a quick fix for PHP Dig. All of the products on our site have item numbers but they aren't searchable - I'm guessing because they're only numbers and PHP Dig doesn't index stand-alone numbers. I want to change the search algorithm so that if somebody searches for an item number in our DB, they're taken straight to that page and bypass the search results.

I'm not familiar with the ins and outs of PHP Dig, so I was hoping somebody could advise me on the best place to insert this logic. Any advice?
