The EEA Faceted Navigation (FacetedNav) gives you a very powerful interface to improve search within large collections of items. No programming skills are required by the website manager to configure the faceted navigation interface, configuration is done TTW. It lets you gradually select and explore different facets (metadata/properties) of the site content and narrow down you search quickly and dynamically.
On the contrary, plone collections are static, in a way that the site admin decides the search criteria and the end user is not able to further sort or filter the presented results.
FacetedNav is fully customizable, site admin may decide that some criteria (facets) must have fixed values while other may be presented as filter options to the web visitor.
FacetedNav may very well replace the standard collection content type, since it covers same functionality and it adds a lot more features.
FacetedNav can also be used as an advanced search for your site.
It comes with plenty of configuration options and features like:
- Easy customizable GUI via drag-n-drop, no restart needed.
- Facets can be set to fixed default values and hidden.
- Facets can be placed in standard search or extended search panels, to not intimidate novice users and have cleaner interface
- Facets can be displayed via several widgets like select, radio, text input, tag cloud, date range and more
- Expandable and collapsible widgets with many values
- Automatically counts number of content items beside each facet value
- Possibility to show or hide the options with zero results (show only the facets which return content)
- Ability to create your custom content types definition to be used as a combination of interface and portal type, presented in a single widget.
- Export of search result in RSS.
- Pleasant user interface based on Ajax JQuery, implemented with "deep linking", so bookmarking a faceted query works, browser history supported.
- Export / Import of faceted settings as XML. Useful to replicate same facets navigation on another site.
- Synchronization of settings across multiple languages, I18N support.
- High performance by caching faceted catalog queries via distributed memory object caching system: memcached
- Smart facets hiding - hide facets criteria if there is only one page of results (This can be explicitly disabled from version 4.6)
- Ability to transform faceted navigable items in search forms by putting them in the 'search mode' (starting with version 4.6)
You can extend faceted navigation functionality by installing the following addons:
- Customized vocabularies
- Multilingual/translation solution
- Cache (memcache)
- Faceted extensions
- Faceted themes
