Done, and closing.

That sounds troubling. Please report if you encounter this again, 
together with: do you get different results when immediately repeating 
the same search? Or do you search from different files, in different 
directories?

Getting different results between searches from c-mode and 
emacs-lisp-mode is to be expected, because the latter searches in all 
load-path as well (and it ends up using Grep in most of those 
directories anyway).

Also done (with a slightly longer value).
