• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) ((dang ma) OR (dang mau)) hoa. hieu van nam xuc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach ty)) ((dang ma) OR (dang mau)) hoa. hieu van nam xuc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach ty)) ((dang ma) OR (dang mau)) hoa. hieu van nam xuc va hanh vai cua tre*.
