maybe someone can find this useful I use something similar to use adsense search on some parts of the website using the title as a search string:
$links[] = "<script language="JavaScript" type="text/javascript"><!-- function search ( mytext ) { document.google.q.value = mytext ; document.google.submit() ; }--> </script><!-- Search Google --><form name="google" method="get" action="http://www.google.com/custom%5C" target="_top"> <input type="hidden" name="q" value=""></input> <input type="hidden" name="sa" value="Search"></input> <input type="hidden" name="client" value="pub-9360264097731242"></input> <input type="hidden" name="forid" value="1"></input> <input type="hidden" name="ie" value="ISO-8859-1"></input> <input type="hidden" name="oe" value="ISO-8859-1"></input> <input type="hidden" name="cof" value="GALT:#008000;GL:1;DIV:#336699;VLC:663399;AH:center;BGC:FFFFFF;LBGC:336699;ALC:0000FF;LC:0000FF;T:000000;GFNT:0000FF;GIMP:0000FF;FORID:1;"></input> <input type="hidden" name="hl" value="en"></input><a href="javascript:search('".$node->title."')">Support GH</a></form><!-- Search Google -->";
