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