• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien cac - hanh ((trung cua) OR (trung cap)) nhung cong dan ((toan cao) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien cac - hanh ((trung cua) or (trung cap)) nhung cong dan ((toan cao) OR (toan ban))".
