• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((nang tao) OR (sang tao)) hoi. ((hieu ve) or (hieu va)) cac tuc va dan hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((nang tao) OR (sang tao)) hoi. ((hieu ve) OR (hieu va)) cac tuc va dan hai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((nang tao) OR (sang tao)) hoi. ((hieu ve) or (hieu va)) cac tuc va dan hai cua te*".
