I do the file selection by using the 'find' command instead. I also use
the 'H' switch of grep/egrep in order to get the file name along with
the relevant code line:

find . -name "*.cpp" -exec egrep -H "csMin.\(|csMax.\(" "{}" ";" | less

I put that in a small script (in attachment of this mail), and it's even
easier:

_ffind "csMin.\(|csMax.\("

or more explicitely:

_ffind . cpp "csMin.\(|csMax.\("
