Here's the code in case the widget is deleted:
<div class='search'>
<form action='/search' class='searchform' method='get'>
<input class='searchbox' name='q' placeholder='' type='text' value='I want to find...' vinput='' onblur='if(this.value=='')this.value=this.defaultValue;' onfocus='if(this.value==this.defaultValue)this.value='';'/>
<input class="searchsubmit" type="submit" value="Search"/>
<div style='clear: both;'></div>
</form>
</div>
