i haven't even got a search.php file. my main page is index.php
what is it, the results page? or just a little search box?
if it's just a search box then you don't really have to include the file, just copy the search box code straight into your main page. as long as the search form leads to the same page in the end, thats all that matters
if it's the result page, then just amend the search.php file directly, and include all your headers and sidebars, or whatever, around it. pretend that it is just a template file
