Get main menu in to my search page
You can customise your search-results.tpl.php by copying this file from the core search module and putting it into your theme directory. You can add your menu in where you like using code:

&lt;div id="menu"&gt;
  &lt;?php print theme('links__system_main_menu', array('links' =&gt; $main_menu)); ?&gt;
&lt;/div&gt;
