Is there a way to search for an attribute that exists but is empty?
NOT _exists_:attributeName
Only returns those where the attribute does not show up on the Identity Cube. But if the value is empty and there is a transform, the Identity attribute is populated with an empty value.
For example, we have a dateFormat transform that if the input is empty the Identity Attribute will still exist.
{
"attributes": {
"inputFormat": "yyyy-MM-dd",
"outputFormat": "ISO8601"
},
"id": "Date Format",
"type": "dateFormat"
}
