• If you are trying to use Boolean operators, they must be ALL CAPS: nho ((hieu lang) OR (chieu sang)) - hanh trung cap nong duong manh ((toan cau) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nho ((hieu lang) OR (chieu sang)) - hanh trung cap nong duong manh ((toan cau) or (toan ban))*".
