Create Web Search for all events for a user

I cannot determine the exact criteria to find all Custom User Monitoring Events and Customer AD Object Monitoring Events for one user.

I can create the search for the events in the Facility but I can't figure out how to select one user (not the user that made the change but the user whose record was modified).

Also, when I do a search for a long time period (7 months), I only get 7742 events returned which is far fewer than when I run this search on the fat client on the CA server.

I did uncheck the 'limit search...' parameter on the Info tab (that ALWAYS trips me up)

TIA
