• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((((nang ma) OR (nang cao))) or (sang ma)) hoa. hieu ve cam luc van thanh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((((nang ma) OR (nang cao))) OR (sang ma)) hoa. hieu ve cam luc van thanh le cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((((nang ma) OR (nang cao))) or (sang ma)) hoa. hieu ve cam luc van thanh le cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((((nang ma) OR (nang cao))) or (sang ma)) hoa. hieu ve cam luc van thanh le cua tre*.
