• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky danh ma hoa. ((((hieu van) OR (hieu va))) OR (lieu va)) nam xuc va hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky danh ma hoa. ((((hieu van) OR (hieu va))) or (lieu va)) nam xuc va hanh vai cua tre".
