Hi All, A question on API queries: We can use the below simple query to search for a specifically defined value of ‘ifMeta_interdomain_id’. Additionally, we would like to get a list of all datasets where the property is defined as any value (i.e. exclude datasets that do not have this property defined). Does anyone know the way to query?

http://.../entities?action=search
{
    "input": "customProperties: ifMeta_interdomain_id=<specific value>",
    "entity": "dataset",
    "start": 0,
    "count": 10
}
