Articles: facets

Starting with Arena 4.0, you are recommended to start using Liferay articles instead of Arena articles. Arena articles will still be supported but will not be further developed.

This portlet is used to show facets, that is, terms, subject groups etc. from Arena articles. A facet augments article searches. Clicking on a facet limits the search result and displays a small icon in the form of a + next to the selected facet.

There are two types of facets for articles:

• Search facet: This will drill-down to refine a search. After activation, the content of the facet reflects the new search result. For example, a search result may include articles in a number of different languages, and you can select to make a new search with only English by clicking English in the facet. A Discovery facet is by default placed on the /articles page.
• Inspirational facet: This works like a table of contents. It does not change on activation. It may be used anywhere, as it does not relate to a search. It is used most commonly on an articles page, as a form of menu to find articles.
