• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky ((nang o) OR (nang ro)) hoi. ((hieu ve) OR (hieu van)) cam duc va danh lai cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky ((nang o) or (nang ro)) hoi. ((hieu ve) OR (hieu van)) cam duc va danh lai cua cu".
• Adding a wildcard symbol may retrieve word variants: te cac ky ((nang o) or (nang ro)) hoi. ((hieu ve) OR (hieu van)) cam duc va danh lai cua cu*.
