• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((nang ma) OR (nang cao)) hoa. hieu qua cam ((xuc va) OR (tuc va)) nang di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((nang ma) OR (nang cao)) hoa. hieu qua cam ((xuc va) or (tuc va)) nang di cua te*".
