Even with Moptions, you can put into the "Text:" line

(AAA|BBB|CCC)

and click on "Search text also in attributes". This is a valid regular
expression with searches for AAA or BBB or CCC. Unfortunately you still can
mistype the values. If I would add check boxes in the find page, it would not
be clear if one searches for an "AND" of several values or an "OR" (Most people
would probably think that they want an "AND" because this happens if they
restrict several attributes).
