Not sure of your input, but
Take a look at the following. You will need to escape for the * as it is a wildcard. Note that the last example did not return anything.

Code:
$ echo **YES **No
**YES **No

$ echo **YES **No | grep "*"
**YES **No

$ echo **YES **No | grep "\*"
**YES **No

$ echo **YES **No | grep "\*\*YES"
**YES **No

$ echo **YES **No | grep "\*\*YET"

Why not just grep for YES,NO without the *?
grep -E "YES|NO"
Gives all lines with YES, or NO

Note for Joeyg's example: shells will try to glob (find matching files names for) the ** characters.

In bash (as an example) you can turn off globbing with
Code:
set -o noglob

The asterisks would need to be escaped from shell, but also from grep:
Code:
grep -Ei "\*\*(yes|no)\*\*" file

Unless the -F option is used. Try:
Code:
grep -Fie '**yes**' -e '**no**' file
