Options window - Filter tab
Filters can be defined to filter in or filter out tests.
Filters can be very complex.
With VIM the process of creating and managing filters has been made as easy as possible. The new filtering logic is extremely flexible, optimized for speed, and was created exclusively for OLMonitor.
Remember you can also create a quick filter by right-clicking any test on the main window and choosing which field to filter out. This filter can later be modified in the options window.
The Filter examples section shows some great examples of filters ranging from simple to complex.
Also this blog post is a good read on using filters and worksheets to efficiently control what shows up.
