I tried to solve problems in vb4.1.1 following by step:

- Find in the navbar template for this code:

<form action="search.php?{vb:raw session.sessionurl}do=process" method="post" id="navbar_search" class="navbar_search">
   <vb:comment><input type="hidden" name="s" value="{vb:raw session.sessionurl}" /></vb:comment>
   <input type="hidden" name="securitytoken" value="{vb:raw bbuserinfo.securitytoken}" />
   <input type="hidden" name="do" value="process" />
   <span class="textboxcontainer"><span><input type="text" value="" name="query" class="textbox" tabindex="99"/></span></span>
   <span class="buttoncontainer"><span><input type="image" class="searchbutton" src="{vb:stylevar imgdir_button}/search.<vb:if condition="(is_browser('ie') AND !is_browser('ie', 7) AND !is_browser('ie', 8))">gif<vb:else />png</vb:if>" name="submit" onclick="document.getElementById('navbar_search').submit;" tabindex="100"/></span></span>
  </form>

Replace with:

 <form action="http://www.yoursite.com/google.php" id="cse-search-box">
    <input type="hidden" name="cx" value="xxxxxxxxxxxxxxxxxxxxx:xxxxxxxxxxx" />
    <input type="hidden" name="cof" value="FORID:9" />
    <input type="hidden" name="ie" value="utf-8" />
            <span class="textboxcontainer"><span><input type="text" value="" name="q" class="textbox" /></span></span>
            <span class="buttoncontainer"><span><input type="image" class="searchbutton" src="{vb:stylevar imgdir_button}/search.<vb:if condition="(is_browser('ie') AND !is_browser('ie', 7) AND !is_browser('ie', 8))">gif<vb:else />png</vb:if>" name="submit" onclick="document.getElementById('navbar_search').submit;" tabindex="100"/></span></span>
		</form>
<script type="text/javascript" src="http://www.google.com/cse/brand?form=cse-search-box&amp;lang=th"></script>
