Activate the "Page preview" tab, and click on the different films to see their different cards (WIT ideas),

You may notice that some of the imported fields are shown as clickable attributes in the table area of the idea : click on a actor name.

You get an error because the index has not been built yet : press Ctrl + Shift + E to build it.

Click again on the actor name.

WIT jumps in the "faceted index" of characters, and you can now seen who played in which films. Some actors played in several films (Grace Kelly, Cary Grant...).

Note : the index is alphabetically sorted. Such a sort would be more efficient for actors if their names came first (name, surname). This is inherited from the imported file.

Click in the index, in the bottom of any page : you get the main index, where we have chosen to map the "Genre" field of the CSV file on the "keywords" idea attribute. This is arbitrary in this sample.
