• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((tu lang) OR (cu lang)) xa hoi. hieu ve cao duc ((va thanh) OR (va tinh)) gian cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((tu lang) OR (cu lang)) xa hoi. hieu ve cao duc ((va thanh) or (va tinh)) gian cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ((tu lang) OR (cu lang)) xa hoi. hieu ve cao duc ((va thanh) or (va tinh)) gian cua te*.
