This is possible with regex.
If you want to search within the current buffer use
(re-search-forward "foo() \{.* bar.*\}")

The task is more difficult if you want to search within all files in a 
directory.
You can either use
find -type f -name "*.cpp" | grep "foo() \{.* bar.*\}"
Or within emacs, by interfacing find and grep.
I also developed erfind for this purpose.
It does not need any thirdparty application and in addition can work on 
windows and linux.
Download it here, copy it to your emacs seach path:
http://scm.mathematek.de/repos.cgi/emacside/zip/emacside.zip

Then load the packages with

(require 'eide-filetools)
(require 'eide-erfind)

You can modify the source for your needs, but in your case maybe this 
should work
M+x erfind-cwd <RET> foo() \{.* bar.*\} <RET>

Hope this helped a little, Louis
