Unfortunately for code browsing, the class name and constructor name are the same. So if you only want to find when a constructor is called, and you search on the class name, you get much more in the results than just the calls to the constructor.
It would be nice if there was a feature in SE where I could tell the cross-reference search that I only want to find where there are calls to the constructor, and not find all references to the name of the class.
