• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ly hang x hoi. hieu ve cau luc ((va phan) OR (van phan)) tai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ly hang x hoi. hieu ve cau luc ((va phan) OR (van phan)) tai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ly hang x hoi. hieu ve cau luc ((va phan) OR (van phan)) tai ((cua tre) or (cuu tre))*".
