• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky ((lang thai) OR (lang hai)) hoi. thien van chat ((xuat ban) OR (quoc ban)) hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky ((lang thai) OR (lang hai)) hoi. thien van chat ((xuat ban) or (quoc ban)) hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: tu cac ky ((lang thai) OR (lang hai)) hoi. thien van chat ((xuat ban) or (quoc ban)) hanh di cua te*.
