A really lazy way to add search to your RW page:
<div id="gsearch">
<form action="http://www.google.com/search">
<input type="text" name="q"/>
<input type="hidden" name="hl" value="en"/>
<input type="hidden" name="sitesearch" value="http://homepage.mac.com/filipp"/>
<input type="submit" value="Search with Google"/>
</form>
</div>
I think you could actually cook up something nice with a Google developer account and XMLHttpRequest…
