I'm trying to get the Search API module to work on my Drupal 7 installation, but I get the following error when I go to Home » Administration » Configuration » Search and metadata » Search API » Default node index:
The server this index currently lies on doesn't support facets. To use facets you will have to move this index to a server supporting this feature.
What steps should I follow, in order to make my server compatible with the Search API module?
