This is inaccurate and misleading.  It might be true for the default
back-end (which AFAIR is Grep), but certainly not for all of them.
What exactly is a "reference" is determined by the back-end search
tool, and some of them understand quite a lot of the programming
language of the source files.

So please correct that blog to avoid misleading people.
