We've developed a new site search for our site, but before I deploy the new one, I'd kinda like to run some split testing to see if it actually gives better conversions.

I had been planning to use Google anlaytics for the split test, just because I use Google for a lot of other analytics. But I'm not sure if Google's split testing is suitable for this task, as I really want to deliver a separate page, rather than some slightly different content, which I think is how Google's test works (though I'm prepared to be corrected on this).

Is it possible to use Google analytics for this, and to count in the test only those users who used the search? Or would I have to use a server-side split test for this?
