Hello

Short Description:
An IQL function Count(<Attribute Name>)

Long Story:

As example you have an objectType "Equipment" with an attribute "Assigned Person" (Referenz)
and now you like to search any Equipment which has more than 1 assigned Person.

Expected:
IQL usage would be

1)
objectType = Equipment AND count("Assigned Person") > 1

2)
objectType = System AND count("CPU") = 1

3)
objectType = Application AND count("Systems") = 0
