i am trying to search for issues submitted during a certain period but exclude those that have been modified by certain users. so far i've got this filter but it does not work
project = iso AND issuetype = Bug AND Status changed from "Ready to Test" to (Open, Closed) after startOfDay() AND Source in (Core, Dev) AND updated >= -10h AND (Not status changed BY x@abc.com) AND (NOT status changed BY y@abc.com)
any ideeas?
