• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu ((tang ma) OR (mang may)) hoi. hieu ((vu cham) OR (va cham)) lo van anh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu ((tang ma) OR (mang may)) hoi. hieu ((vu cham) or (va cham)) lo van anh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu cach tu ((tang ma) OR (mang may)) hoi. hieu ((vu cham) or (va cham)) lo van anh tai cua tre*.
