• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) or (sach y)) sang ((dai hoi) OR (dai moi)). hieu va cao suc va thanh lap cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) sang ((dai hoi) OR (dai moi)). hieu va cao suc va thanh lap cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach y)) sang ((dai hoi) OR (dai moi)). hieu va cao suc va thanh lap cuu tre*".
