• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho lieu) OR (co lieu)) tinh - hanh tinh cua thong cong ((bac thanh) OR (bac thanhh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) OR (co lieu)) tinh - hanh tinh cua thong cong ((bac thanh) or (bac thanhh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) OR (co lieu)) tinh - hanh tinh cua thong cong ((bac thanh) or (bac thanhh)) cau*.
