Dear GBIF API users, I would like to get some GBIF index statistics, e.g., Is it possible to obtain all indexed fields in the elasticsearch occurrence index? I already tried to get the mapping http://api.gbif.org/v1/_mapping?pretty and http://api.gbif.org/v1/occurence/_mapping?pretty and I also tried it with the search (http://api.gbif.org/v1/occurrence/search) and a facet on _field_names. { "query": { "match_all": {} }, "aggs": { "Field Names": { "terms": { "field": "_field_names" }} } } Unfortunately, both doesn't work. Is there any other opportunity to get all indexed fields?
