• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tham thang ma hoa. hieu ((van cau) OR (van hau)) ((truc va) OR (thuc vat)) hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tham thang ma hoa. hieu ((van cau) OR (van hau)) ((truc va) or (thuc vat)) hanh vi cuu tre".
