• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky anh ((tay thai) OR (lay thai)). hieu va cac loc ((va hanh) OR (va danh)) vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky anh ((tay thai) OR (lay thai)). hieu va cac loc ((va hanh) or (va danh)) vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu cac ky anh ((tay thai) OR (lay thai)). hieu va cac loc ((va hanh) or (va danh)) vi cuu tre*.
