HTML Search Box Help

[tynco]

Hi I was wondering if anyone knew how to add text after a search. I have a google search and I want to customize it so it says "+Video" after what i search. so if i searched "Guitar Lessons" it would search "Guitar Lessons +Video." Thank you for you time

My code so far

<!-- GOOGLE -->
<font color="666666">
Google<br />
<form method="get" target="_blank" action="http://www.google.com/search"> <input name="q" maxlength="255" type="text" /> <input value="Go" type="submit" /> </form>
<p>

<input name="q" maxlength="255" type="text" /> 
<input value="Go" type="submit" /> 
</form>
