What are facets?
When you get a search result using the Search Engine or the tabs labelled Clientele and Subject Areas, the items in the left column are called Facets.
Facets are categories for classifying videos and playlists, which allow you to refine your search. In CVE, there are eight facet categories, each of which contains several elements. The number between parentheses beside each item indicates the number of videos associated with it. When you click on an element of a particular facet, the elements of the other facets will be updated accordingly.
