Do a stream query with tags filter

Hi,

According to this documentation,  https://support.ptc.com/help/thingworx_hc/thingworx_8_hc/en/index.html#page/ThingWorx/Help/Composer/Things/ThingServices/QueryParameterforQueryServices.html,

we should be able to do a query with those filters:

TAGGED or NOTTAGGED filter
var query = {
 "fieldName": "tags",
 "type": "NOTTAGGED",
 "tags": [
 {
 "vocabulary": "Applications",
 "vocabularyTerm": "Testing"
 },
 {
 "vocabulary": "Plants",
 "vocabularyTerm": "Sedona"
 }
 ]
};

or with those:

var query =
{
 "filters": {
 "type": "And",
 "filters": [
 {
 "type": "GT",
 "fieldName": "Duration",
 "value": "12"
 },
 {
 "type": "TaggedWith",
 "fieldName": "tags",
 "tags": "MaintenanceIssues:PowerOutage"
 }
 ]
 }
}; 

But it seems that none of them works with tags. Can someone confirm this troubleshouting?

Thanks.
