Do you mean grep for both or either?

grep -r "foo\|bar" ~/public_html

will show all hits with *either* "foo" or "bar"

grep -r "foo.*bar" ~/public_html

will show all hits with "foo" before "bar" in the same line

grep -r "bar.*foo" ~/public_html

will show all hits with "bar" before "foo" in the same line

grep -r "\(bar.*foo\)\|\(foo.*bar\)" ~/public_html

will show all hits with bar and foo on the same line in any order

If you are getting more complex than that, you should probably use perl.
