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