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