    // Using OR.  The syntax is OR <criteria1> <criteria2>. 
    // The "OR" comes first, followed by each criteria.
    // For example, to match all emails with "Help" or "Question" in the subject.
    // You'll notice that literal strings may be quoted or unquoted.
    // If a literal contains SPACE characters, quote it:
    Move "OR SUBJECT Help SUBJECT Question" To sOrSearch
