Couldn't create range_filter for search index(commerce price) I'v a Search Api indexing server, I've added an index for price on it, and I want to create a price range filter on my created view.
I've added the price to the CONTEXTUAL FILTERS on my created view, but when i go to the contextual_range_filter configuration page (admin/config/content/contextual-range-filter), I couldn't see the indexed price field, so I couldn't use the contextual_range_filter.

Note : I need to use Contextual Range Filter module to be able to use the filters with services.

How to make it work by default?
There is an opened issue for the module contextual_range_filter with search_api and the patch patch-contextual-range-filter-search-api.txt will make the range filter work with views based on search api though you could use it for a resource for services.

Another way of achieving that scenario is to use search_api_ranges but it won't be controlled by services module.

Hope that helps with your case.
