• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) v tang van hoi. lieu va phan thuc xa xanh ((di cua) OR (doi cua)) su~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) v tang van hoi. lieu va phan thuc xa xanh ((di cua) or (doi cua)) su~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) v tang van hoi. lieu va phan thuc xa xanh ((di cua) or (doi cua)) su*.
