• If you are trying to use Boolean operators, they must be ALL CAPS: cho chu xanh - ((hanh tang) OR (hanh trinh)) cua thong huong dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xanh - ((hanh tang) or (hanh trinh)) cua thong huong dan ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - ((hanh tang) or (hanh trinh)) cua thong huong dan ((than cau) OR (than cap))*.
