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**.

Upgrade to version 10.0+
========================
* Within "Plone > Site setup > Add-ons" click on upgrade button available for
  EEA Faceted Navigation;
* Only if the above step didn't work for you. Within "Plone > Site setup > Add-ons"
  uninstall EEA Faceted Navigation and Install it again;
* If you have third-party Faceted Navigation Widgets (registered outside
  eea.facetednavigation package) you will need to upgrade them to z3c.form
  and explicitly register JS/CSS resources within registry.xml/cssregistry.xml/jsregistry,xml
  Take `faceted text widget `_  as an example;

Main features
=============
It comes with plenty of configuration options and features like:

1. Easy customizable GUI via drag-n-drop, no restart needed.
2. Facets can be set to fixed default values and hidden.
3. Facets can be placed in standard search or extended search panels,
   to not intimidate novice users and have cleaner interface
4. Facets can be displayed via several widgets like select, radio,
   text input, tag cloud, date range and more
5. Expandable and collapsible widgets with many values
6. Automatically counts number of content items beside each facet value
7. Possibility to show or hide the options with zero results
   (show only the facets which return content)
8. Ability to create your custom content types definition to be used as a
   combination of interface and portal type, presented in a single widget.
9. Export of search result in RSS.
10. Pleasant user interface based on Ajax JQuery, implemented with "deep linking",
    so bookmarking a faceted query works, browser history supported.
11. Export / Import of faceted settings as XML. Useful to replicate same facets
    navigation on another site.
12. Search engine friendly, disabling javascript acts as a normal collection
    batch list.
13. Synchronization of settings across multiple languages, I18N support.
14. High performance by caching faceted catalog queries via `distributed memory
    object caching system: memcached `_
15. Smart facets hiding - hide facets criteria if there is only one page of
    results (This can be explicitly disabled/enabled from version 4.6.
    It is also disabled by default for new faceted navigable pages starting
    with version 5.2)
16. Ability to transform faceted navigable items in search forms by
    putting them in the 'search mode' (starting with version 4.6)
17. Ability to enable/disable Plone portlets left and right columns within
    faceted navigable contexts (starting with version 4.1. Both disabled by
    default for new faceted navigable pages starting with version 5.2)

Install
=======

* Add eea.facetednavigation to your eggs section in your buildout and
  re-run buildout::

    [buildout]
    eggs +=
      eea.facetednavigation

* You can download a sample buildout from:

  - https://github.com/eea/eea.facetednavigation/tree/master/buildouts/plone4
  - https://github.com/eea/eea.facetednavigation/tree/master/buildouts/plone5

* Or via docker::

    $ docker run --rm -p 8080:8080 -e ADDONS="eea.facetednavigation" plone

* Install *EEA Faceted Navigation* within Site Setup > Add-ons

Getting started
===============

* Go to your working space and add a **Folder** and within **Actions** menu
  click on **Enable faceted navigation**.
  See more on the dedicated youtube channel: `EEA Web Systems Training`_

Faceted settings
================

**Faceted settings** is a menu that appears once you enable Faceted navigation
within your context next to the **Actions** menu and it allows you to perform
the following actions:

Configure
---------
Configure Faceted Navigation TTW.

Enable/disable left portlets
----------------------------
This allows you to gain more space for faceted navigation pages by disabling
Plone portlets left column.

Default: **disabled** (*starting with version 5.2*)

Enable/disable right portlets
-----------------------------
This allows you to gain more space for faceted navigation pages by disabling
Plone portlets right column.

Default: **disabled** (*starting with version 5.2*)

Enable/disable smart facets hiding
----------------------------------
Hide facets criteria if there is only one page of results.

Default: **disabled** (*starting with version 5.2*)

Autocomplete widget
===================

Setup
-----

You can enhance and boost search by replacing **ZCatalog** with **Apache Solr**, see `collective.solr`_. Thus:

* Add **collective.solr** to your eggs section in your buildout and re-run buildout::

    [buildout]
    eggs +=
      collective.solr

* With **Plone 5** you'll need to use a more recent version::

    [versions]
    collective.solr = >= 8.0.0b1

* Start solr::

    $ docker run -p 8983:8983 eeacms/solr

* Install **collective.solr** within **Site Setup > Add-ons**

* **Setup and reindex** Solr within **Site Setup > Solr settings**

* Add or replace **Text** widgets with **Text field with suggestions** within your faceted enabled items.

i18n
----

To include a specific select2 locale, French for instance, you can add a resource `++resource++select2/select2_locale_fr.js` in portal_javascripts (Plone 4). It needs to be after the select2.min.js resource. (You need eea.jquery 8.7 minimum)

Suggestions
-----------

You can add a new autocomplete source by registering a IAutocompleteSuggest browser view, you can see an example in
`eea/facetednavigation/tests/autocomplete.py `_ and
`eea/facetednavigation/tests/autocomplete.zcml `_

You also need to configure Solr to include **/suggest** requestHandler. Within your **solrconfig.xml** add::

    
    
      
        suggest
        org.apache.solr.spelling.suggest.Suggester
        org.apache.solr.spelling.suggest.fst.WFSTLookupFactory
        Title
        0.005
        true
      
    

    
      
        true
        suggest
        10
        true
        xml
      
      
        suggest
