Intersection is used to search for all selected events: "Find x and y."
Intersection lets you tell the analyzer to search the trace for any packet
having all of the selected events.
Exclusion is used to exclude selected traffic from the trace. Exclusion is
used with Union and Intersection --i.e., you select Exclusion with Union or
Intersection.
• Exclusion + Union -- tells BTTracer to exclude packets with any of the
specified events.
• Exclusion + Intersection -- tells BTTracer to exclude packets with all of the
specified events.
