• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang ma hoi. hieu ((ve cham) OR (va cham)) ((xuc va) OR (thuc vat)) hanh lai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang ma hoi. hieu ((ve cham) OR (va cham)) ((xuc va) or (thuc vat)) hanh lai cua tre*".
