If you have a process instance with a variable "x" and the value "5" from type "Integer":

• use cockpit to filter after this process instance
• open the process definition view and add variable filter
• enter the following variable filter:
  "x >= 4.5"

-> The process instance with the variable "x" and value "5" will not occur in the the result set of process instances

(for implementation see:

• processInstance.xml in Cockpit
• implement the behavior in Java)
