• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky ((tang ma) OR (sang ma)) hoa. hieu ve cam ((xuc van) OR (luc van)) dinh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky ((tang ma) or (sang ma)) hoa. hieu ve cam ((xuc van) OR (luc van)) dinh vi cua tu*".
