The Purpose: allowing your users to search differently
Ajaxed search engines are all over the place ? literally. 
Whenever a large amount of items is available, be it houses for rent 
or computer spare parts, providing your users with a fast, structured, faceted search 
can be one thousand times more efficient, rather than letting your visitors sink into hundreds of web pages, 
hoping they?ll find what they need ? almost by chance. 
This tool does not replace or try to extend the build in textual search feature of WordPress; 
it aims to provide a quick bootstrap to an ajaxed search engine, demonstrating how easy it can be to turn 
your website into a powerful search tool, without installing a huge and bloated code.
It is easy to hack and to extend at your will.

<h3>Main Features</h3>
Let your users search combining different criterias: Filter by name, category, tag, or custom field (=1). 
Sort results by date, name or custom field (numeric)
<h3>Typical usage</h3>
Searchy is a customizable search engine composed of two elements: the search filters – typically a filters column, and the search results.
Use the searchy_filter shortcode or the built-in widget to show the filters column. 
Place the searchy_results shortcode in a WordPress page to show the sort bar and the search results. 
Of course those go in square brackets in a chosen Page. 
You can place them one after the other, having searchy_filter and searchy_results close, 
Or get fancy building your custom layout, placing some do_shortcode calls wherever you want.
