• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky tang van hoi. ((hieu va) OR (hieu van)) cham tuc va thanh vi hoa viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky tang van hoi. ((hieu va) or (hieu van)) cham tuc va thanh vi hoa viet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ky tang van hoi. ((hieu va) or (hieu van)) cham tuc va thanh vi hoa viet*.
