• If you are trying to use Boolean operators, they must be ALL CAPS: vien bach ky lang xa hoi. hieu ((va tham) OR (van tham)) sac ((van dinh) OR (va dinh)) di cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vien bach ky lang xa hoi. hieu ((va tham) or (van tham)) sac ((van dinh) OR (va dinh)) di cau tre".
• Adding a wildcard symbol may retrieve word variants: vien bach ky lang xa hoi. hieu ((va tham) or (van tham)) sac ((van dinh) OR (va dinh)) di cau tre*.
