• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((mang may) or (tang ma)) hoa. hieu van cam qua ban hang ((vai cua) OR (lai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((mang may) OR (tang ma)) hoa. hieu van cam qua ban hang ((vai cua) OR (lai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((mang may) or (tang ma)) hoa. hieu van cam qua ban hang ((vai cua) OR (lai cua)) triet*".
