• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang ma hoi. hieu ((va nam) OR (le nam)) thuc ((dang hanh) OR (dang van)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang ma hoi. hieu ((va nam) or (le nam)) thuc ((dang hanh) OR (dang van)) vi cua te".
