Faceted Search

It is more than a search interface, this is an information navigation and discovery tool.

The interface exposes metadata in such a way that users can build their queries as they go, refining or expanding the current query, with results automatically reflecting the current query. This interface also combines free-text search, fully leveraging Drupal's search engine. It avoids complex search forms, and never offers facets that would lead to empty result sets.

This package is actually a collection of modules:
- Faceted Search: Provides the search framework and API.
- Faceted Search UI: Provides the search user interface.
- Faceted Search Views: Allows to use Views to display the search results.
- Author Facet: Allows users to refine the current search based on content author.
- Content Type Facet: Allows users to refine the current search based on content type.
- Date Authored Facet: Allows users to refine the current search based on content creation date.
- Taxonomy Facets: Allows users to search content through taxonomy. Any vocabulary can become a facet that can be used to refine the current search.
- Field Keyword Filter: Allows users to perform keyword searches restricted by field. Requires the Field Indexer module.
Installation
