Using find for finding files is best.  Really having grep do directory
processing is a misfeature.

If you want bash/csh style file globbing them you can just use bash
directly, for the current directory anyway.

  echo {no,uh}* | xargs grep

For that plain old find is best.

  find D -name 'no*' -o -name 'uh*' | xargs grep

Try:

  grep -r abc .
