directory excludes in search directory

I'd love to have the possibility to exclude certain subdirectories from a directory search in the Search and Replace functionality. I quite often search local checkouts of subversion or cvs and it mostly is waste of resources to search the .svn and .cvs subdirectories as they contain metadata of the specific versioning system. ‘--exclude-dir=dir’ (Exclude directories matching the pattern dir from recursive directory searches.) option of GNU grep can is what I imagine.
