• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu tang van hoe. hieu ve chat soc ((((va thanh) OR (va tinh))) OR (va kinh)) hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu tang van hoe. hieu ve chat soc ((((va thanh) OR (va tinh))) or (va kinh)) hai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach thu tang van hoe. hieu ve chat soc ((((va thanh) OR (va tinh))) or (va kinh)) hai cua triet*.
