• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu tinh - hanh trinh ((le dang) OR (le tang)) cong dan ((phan dau) OR (than cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh trinh ((le dang) OR (le tang)) cong dan ((phan dau) or (than cap))*".
