• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((sang tao) or (mang may)) hoi. hieu qua cam ((luc va) OR (duc va)) xanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((sang tao) OR (mang may)) hoi. hieu qua cam ((luc va) OR (duc va)) xanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((sang tao) or (mang may)) hoi. hieu qua cam ((luc va) OR (duc va)) xanh di cua te*".
