Check out my screenshot
Here is the code of what I did:

<table border="0"  width="100%">
  <tr><!-- Row 1 -->
<td>    <center>

<!--searchSTART -->
              <form action="search.php?do=process" method="post" name="vbform" id="searchform">
<input type="hidden" name="s" value="" />
<input type="hidden" name="do" value="process" />
<input type="hidden" name="searchthreadid" value="" />
                <input type="text" class="alt1" name="query" size="40" onfocus="this.value=''" value="$vbphrase[srechercher_defaut]" />
               <input type="submit" class="button" value="Search CPS KB" style="vertical-align: middle;"/>
              </form>
               
<!--searchEND-->


</td><!-- Col 1 --></center>


<!--Google Start-->
 <td>
    <center>
<form method="get" action="http://www.google.com/custom" target="google_window">
