Finding constructors

Hello everybody,

I need to find all calls of some functions in my project. I'm using GNU 
Global like this:

global -a -r -x funcName

The problem is, that constructors have the same identifier as the class, 
so when I try to find all calls of some constructor, I get a long list 
of declarations too.

Is there any way to restrict search only to functions?

I've tried '-s', but the result was still the same.

Thank you very much,
Martin
