• If you are trying to use Boolean operators, they must be ALL CAPS: hoc tieu tinh - ((canh tinh) OR (tcanh tinh)) cua ((nhung cong) OR (thong cong)) dang van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc tieu tinh - ((canh tinh) or (tcanh tinh)) cua ((nhung cong) OR (thong cong)) dang van ban".
