• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ((ky dang) OR (ky nang)) tay hoi. thien van nam tuc va hanh sua cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) or (te cao)) ((ky dang) OR (ky nang)) tay hoi. thien van nam tuc va hanh sua cua tre*".
