• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) tinh - thanh trung ((cap thong) OR (chap thuong)) hoang van than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) tinh - thanh trung ((cap thong) or (chap thuong)) hoang van than cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) tinh - thanh trung ((cap thong) or (chap thuong)) hoang van than cap*.
