  you could do 10 commands on nothing more than variations on grep:

  grep -r <string> ...		as you mentioned above
  grep -rw <string> ...		must be separate word
  grep -rwl <string> ...	print only file name, which inspires

  $ vi $(grep -rwl <string .)

that last one using command substitution to take the output of the
grep command, and make it the arguments to the vi command.  i use that
last variation -- using grep to generate the arguments for another
command -- literally on a daily basis.
