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