Convert facets on Search Api facet sources to use the display plugin.

File

./facets.install, line 34

Update hooks for the facets module.

Code

function facets_update_8001() {

  // We changed the way we work with search api facet sources, we're now using
  // the SearchApiDisplay plugins that search api ships with. This consolidates
  // the external points for facets, sorts, autocomplete and others. This
  // refactor made us a better member of the Search API family. It also makes it
  // easier for other modules that provide a display to support facets, for
  // example, for the search_api_page module.
  //
  // This only works for the 3 default plugins that we previously shipped. So
  // only views that have a page, block, or rest display. The id will get
  // replaced from views_page:foo to search_api:views_page__foo.
