In a couple of large projects, trying to do a structural search of
class $Class$ extends $foo$ {}
using a scope of 'class heirarchy' fails. The dialog to select the root of the class hierarchy to search appears and permits selection of a class. However, the search is shown as 'scanning project files', instead of being properly restricted to the class hierarchy. Looking at the results, this is indeed the case. The search is correctly restricted to the class hierarchy when run in IntelliJ 5.1 (build 4267).

I have been unable to reproduce this in a small project.

Issue was resolved
