• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang ma hoa. hieu va ((cam dua) OR (chay dua)) ban thanh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang ma hoa. hieu va ((cam dua) or (chay dua)) ban thanh lai cua te".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang ma hoa. hieu va ((cam dua) or (chay dua)) ban thanh lai cua te*.
