Version: 0.3
Date: 05/01/10



This plugin enables a feature called "suggest". Whenever you 
type a character in the search field of your blog site, suggestions 
are being presented. You can select these suggestions and hit enter, 
to execute a search request.

For this plugin I used a javascript "library" of Google's Suggest 
Search. I modified it, to adjust style and functionality , so that 
it works with Wordpress. I tested it with Firefox 1.0 and IE 6.0 (SP1). 



Files: suggest.php - plugin file used by Wordpress
	   /suggest/suggest_data.php - fetches data from Wordpress database
	   /suggest/ac.js - modified javascript library
	   
	   

Installation / Configuration:

1. Copy "suggest.php" and folder (and content) "suggest" into /wp-content/plugins directory.
   Depending on the URI of your blog, you might need to configure the directory of the plugin (step 4).

2. Open index.php and search for a html form called "searchform" (in my case I searched for '<form id="searchform"')
   Add a name to the form tag: 'name="searchform"'
   Add the attribute 'autocomplete="off"' to the input field with the id "s"
   Change button name from "submit" to "subButton"
   
   my original form:
   
   <form id="searchform" method="get" action="<?php echo $PHP_SELF; ?>">
   	<div>
   		<input type="text" name="s" id="s" size="15" /><br />
   		<input type="submit" name="submit" value="<?php _e('Search'); ?>" />
   	</div>
   </form>
   
   my form after modification:
   
   <form id="searchform" name="searchform" method="get" action="<?php echo $PHP_SELF; ?>">
   	<div>
   		<input type="text" name="s" id="s" size="15" autocomplete="off"/><br />
   		<input type="submit" name="subButton" value="<?php _e('Search'); ?>" />
   	</div>
   </form>
   
3. Activate plugin

4. Open "suggest.php" to configure the plugin. Since version 0.3, it's possible to configure colors and font
   of the dropdown, presenting the suggestions. Furthermore it's possible to configure the 
   number of suggestions presented. You can also configure the directory of the plugin, which might be 
   necessary for your blog.
