Searching Closed incidents for statistics

Im trying to look back at all incidents that have been assigned to my team, inm basically trying to get a list where the update history has an "assignment change" action applied and i can then use my teams name.

will this bring back all incidents regardless of what state they are currently in. i want to see the number of incidents that get assigned and closed in a monthly period.

all efforts to attempt this in the search function have failed, i get nothing back at all.
