• Performing a fuzzy search may retrieve terms with similar spellings: te sach y sang ((ma hoi) OR (mai hoi)). thien ((van lam) or (van cau)) duc va tinh bao cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y sang ((ma hoi) OR (mai hoi)). thien ((van lam) OR (van cau)) duc va tinh bao cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y sang ((ma hoi) OR (mai hoi)). thien ((van lam) or (van cau)) duc va tinh bao cua tre*".
