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