• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((xang xa) OR (dang xay)) hoi. lieu va cam xuc va ((thanh nha) OR (thanh nhan)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((xang xa) or (dang xay)) hoi. lieu va cam xuc va ((thanh nha) OR (thanh nhan)) cua viet".
• Adding a wildcard symbol may retrieve word variants: su sach ty ((xang xa) or (dang xay)) hoi. lieu va cam xuc va ((thanh nha) OR (thanh nhan)) cua viet*.
