• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) xanh - thanh trung cua thong cong thanh ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) xanh - thanh trung cua thong cong thanh ((toan tap) or (toan ban))*".
