Provide option to facet on all facetable fields in a Search request
Some applications can have a large number of facets and it is inconvenient to have to specify them all explicitly in the Search API, as reported here: http://stackoverflow.com/questions/28542665/azure-search-what-if-i-have-a-lot-of-facets
If there were an option like facet=* that returned facets on all facetable fields, that would be easier for such cases.
Thank you for your feedback. While it is unlikely we’ll address this suggestion in the near future, we’ll reassess based on the number of votes it receives.
