• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ((ky sang) OR (ky tang)) ma hoi. hieu van pham duc ((hoa doanh) OR (va danh)) ban cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ((ky sang) OR (ky tang)) ma hoi. hieu van pham duc ((hoa doanh) or (va danh)) ban cua te*".
