Google Powered Search

Below is what I have done to integrate the adsense google search with the Drupal CMS.

1. Add the rewrite rule to ".htaccess" file so the search query gets directed to the search page:
   
     RewriteCond %{QUERY_STRING} ^domains=linuxweblog.com&q=([^&]+)&.*$
  RewriteRule ^.*$ index.php?q=search&keys=%1 [L]

   This should come before any other rules, so put it just after the "RewriteEngine on" line. Don't forget to replace linuxweblog.com with your own.

2. Add a "google_search()" function in the "search.module" file to return the Search box and the results. The code can be generated from your adsense account. Here is what I have -- note the query text is pre-filled into the search box:
   

   function google_search() {
   
           $keys = isset($_GET['keys']) ? $_GET['keys'] : $_POST['keys'];
           return t("
                   <p><hr /></p>
                   <h2>Google Powered Search Results</h2>
                   <p>%google_search</p>
                   ", array('%google_search' => '
                   <div align="center">
                   <!-- SiteSearch Google -->
                   <form method="get" action="http://linuxweblog.com/search-results" target="_top">
                   <table border="0" bgcolor="#ffffff">
                   <tr><td nowrap="nowrap" valign="top" align="left" height="32">
                   <a href="http://www.google.com/">

                   </td>
                   <td nowrap="nowrap">
                   <input type="hidden" name="domains" value="linuxweblog.com"></input>
                   <input type="text" name="q" size="31" maxlength="255" value="' . $keys . '"></input>
                   <input type="submit" name="sa" value="Search"></input>
                   </td></tr>
                   <tr>
                   <td> </td>
                   <td nowrap="nowrap">
                   <table>
                   <tr>
                   <td>
                   <input type="radio" name="sitesearch" value="linuxweblog.com" checked="checked"></input>
                   <font size="-1" color="#000000">LinuxWebLog.com</font>
                   </td>
                   <td>
                   <input type="radio" name="sitesearch" value=""></input>
                   <font size="-1" color="#000000">Web</font>
                   </td>
                   </tr>
                   </table>
                   <input type="hidden" name="client" value="pub-3520033732422687"></input>

                   </td></tr></table>
                   </form>
                   <!-- SiteSearch Google -->
   
                   <!-- Google Search Result Snippet Begins -->
                   <div id="googleSearchUnitIframe"></div>
                   <script type="text/javascript">
                   var googleSearchIframeName = "googleSearchUnitIframe";
                   var googleSearchFrameWidth = 600;
                   var googleSearchFrameborder = 0 ;
                   var googleSearchDomain = "www.google.com";
                   </script>
                   <script type="text/javascript" src="http://www.google.com/afsonline/show_afs_search.js">
                   </script>
                   <!-- Google Search Result Snippet Ends -->
                   </div>
                   '));
   }
   

3. Now in the "search_view()" function concatenate the search results just before printing the page:

       $output .= google_search();
       print theme('page', $output, t('Search'));
   

That's it. Test it out and see how it works!!
