• If you are trying to use Boolean operators, they must be ALL CAPS: ((((ho chieu) OR (hoc thieu))) OR (theo chieu)) sang - hanh dinh cua thong cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ho chieu) OR (hoc thieu))) or (theo chieu)) sang - hanh dinh cua thong cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((((ho chieu) OR (hoc thieu))) or (theo chieu)) sang - hanh dinh cua thong cong dan toan cau*.
