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