Foren / Cotonti / General / Search Form

Hey Cotonti, just out of curiosity, the code below, can it be used to just search the forums or a specific forum? Or even specific page sections? I think I did this on Sedito but forgot how. Any help would be appreciated, thanks!

Note: I’m using the latest version of Genoa if that means anything.

<form id="search" name="search" action="plug.php?e=search" method="post">
		<input type="hidden" name="a" value="search" />
		<input type="text" name="sq" value="" maxlength="40" />
		<input type="submit" value="{PHP.L.Search}" />
	</form>
