Fogbugz: Is there a way to search for all cases that a specific user made a specific edit

For example, search for editedBy:<USER> madeChange:"changed estimate field" (poss开发者_如何学运维ibly: editedOn:Yesterday).

Is this possible?

Sorry, it's not possible to do this. One very useful one would be: editedbyme:yesterday. It's not possible to combine criteria like this to restrict. editedby:me edited:yesterday gives you everything that's been edited by you (ever) that was edited (by anyone) yesterday.
