• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky ((mang mayi) OR (mang may)) hoi. ((hieu ve) OR (hieu va)) chat xuc va xanh tri cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky ((mang mayi) or (mang may)) hoi. ((hieu ve) OR (hieu va)) chat xuc va xanh tri cua tre*".
