Search only in files that match a pattern with ack

Can ack search only through files that match a specific 'glob' pattern (eg: search for foo in all files named "bar*.c"). The command ack foo "bar*.c" only works in the current directory. Note: I know it's possible with find -exec: find . -name "bar*.c" -type f -exec ack foo {} + But I would like a small and simple ack command, because find doesn't skip version control directories.
