[API-users] numOccurrences always 0 for species

[Markus Döring]

Hi Peter,
I am surprised we show numOccurrences in the search results. As this is changing in real time we cannot store that in our search index.
I would think this property should not be exposed in species search results. The best way to get occurrence counts is using the occurrence metrics service btw, not the search:

http://api.gbif.org/v1/occurrence/count?taxonKey=3134959 <http://api.gbif.org/v1/occurrence/count?taxonKey=3134959>
http://api.gbif.org/v1/species/3134959 <http://api.gbif.org/v1/species/3134959>
