IRIS.tedit in Domino/Notes 8.5

In Notes R7 we could get the query string from the search bar by using the child class IRIS.tedit. In Notes 8.5 thiis class is no longer defined as a child class under Notes. Is there a different parent/child class to use that defines the search bar in Notes 8.5?

Subject: It is still IRIS.tedit, but deeper down in the hierarchy?!?
