In the Faceted Search Ticket its stated this:
By default, faceted searches are not enabled. To enable faceted search in the UI, open the index.html file and enter:
in the mflix object.
Once implemented, the available movie search parameters will reflect the other search criteria.
I didn’t find any index.html to enter this, the index.html files present didn’t show any kind of mflix object to edit, then I ignored this part and did the ticket anyway, but it did make me waste some time looking for it, please review this ticket!!
