• If you are trying to use Boolean operators, they must be ALL CAPS: mon triet tinh - hanh ((trinh cua) OR (tinh cua)) thuong duong anh ((tuan cao) OR (nang cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "mon triet tinh - hanh ((trinh cua) OR (tinh cua)) thuong duong anh ((tuan cao) or (nang cao))*".
