• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y sang ((me hoi) OR (xa hoi)). lieu van ((thanh soc) OR (nhanh soc)) va thanh di cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y sang ((me hoi) or (xa hoi)). lieu van ((thanh soc) OR (nhanh soc)) va thanh di cua viet".
• Adding a wildcard symbol may retrieve word variants: su sach y sang ((me hoi) or (xa hoi)). lieu van ((thanh soc) OR (nhanh soc)) va thanh di cua viet*.
