• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc dieu) OR (hoc thieu)) tinh - hanh trung van dung cong ((vang thuat) OR (vuong thuat)) do*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc dieu) or (hoc thieu)) tinh - hanh trung van dung cong ((vang thuat) OR (vuong thuat)) do*".
