• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) ky ((mang may) OR (tang ma)) hoi. hieu ve cham luc va danh va su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su sach)) ky ((mang may) or (tang ma)) hoi. hieu ve cham luc va danh va su triet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su sach)) ky ((mang may) or (tang ma)) hoi. hieu ve cham luc va danh va su triet*.
