• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su sach)) o ((lang xa) OR (lang ha)) hoi. hieu ve cac cuoc ban thanh lap cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su sach)) o ((lang xa) OR (lang ha)) hoi. hieu ve cac cuoc ban thanh lap cua viet".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su sach)) o ((lang xa) OR (lang ha)) hoi. hieu ve cac cuoc ban thanh lap cua viet*.
