• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky lang xa hoi. hieu ((van cam) OR (van cau)) luc va ((hang dien) OR (nhan dien)) cu tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky lang xa hoi. hieu ((van cam) or (van cau)) luc va ((hang dien) OR (nhan dien)) cu tren".
• Adding a wildcard symbol may retrieve word variants: thu san ky lang xa hoi. hieu ((van cam) or (van cau)) luc va ((hang dien) OR (nhan dien)) cu tren*.
