• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chau) OR (hoi chu)) tinh - hanh chinh sua nhung cong ((vang toan) OR (quang trung)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chau) OR (hoi chu)) tinh - hanh chinh sua nhung cong ((vang toan) or (quang trung)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chau) OR (hoi chu)) tinh - hanh chinh sua nhung cong ((vang toan) or (quang trung)) cau*.
