google search

hello sir or madam, i am trying to implement something very similar to your "whole site" search in a web page of my own, and i'm very curious how you accomplished that. i imagine that you have some sort of onsubmit function going on, but i'm really curious how you sent the value of the submitted field to a google search. i have quite a bit of experience with php and some with javascript, i just haven't been able to find anything else online. any info you have would be helpful thanks eli duke
