• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ty hang) OR (thi hang)) va hoa. hieu ve cam xuc va hanh di ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty hang) OR (thi hang)) va hoa. hieu ve cam xuc va hanh di ((cuu tre) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty hang) OR (thi hang)) va hoa. hieu ve cam xuc va hanh di ((cuu tre) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty hang) OR (thi hang)) va hoa. hieu ve cam xuc va hanh di ((cuu tre) or (cau treo))*.
