• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) tinh - hanh trung cua nhung huong dan ((than ban) OR (than man))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (hoc thieu)) tinh - hanh trung cua nhung huong dan ((than ban) or (than man))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (hoc thieu)) tinh - hanh trung cua nhung huong dan ((than ban) or (than man))*.
