Go into player search, then search conditions. There will be icons in there which I assume are the ones you're looking for, they have the meaning of each there when you hover over them.

One that isn't there is the blueish circle with a rectangle in it, it means that someone has queued for the Duty Finder. Another is the red circle with a horizontal jolt going through it, it means someone is disconnecting from the game (via network issue,) or just logging out. Hope this helps!
