A faceted search is one that allows you to drill down by various fields: price, size, colour, shipping location etc. It complements a free text search rather than replaces it.
Using this plugin, you can create a faceted search interface for your pages, posts, or any other custom post type. You can add “facets” for:
<ul>
<li>Taxonomies</li>
<li>Custom fields</li>
<li>Dates (day, week, month or year)</li>
<li>Author</li>
</ul>
These facets are widgets that can be easily changed in the admin interface.
You can have multiple search pages for different post types. If your WordPress installation uses multi-site, you can search across the different sites.
