• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu manh - ((anh hoan) OR (anh toan)) cua thang long thanh ((hoa tin) OR (hoa dan))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu manh - ((anh hoan) OR (anh toan)) cua thang long thanh ((hoa tin) or (hoa dan))~".
• Adding a wildcard symbol may retrieve word variants: doc hieu manh - ((anh hoan) OR (anh toan)) cua thang long thanh ((hoa tin) or (hoa dan))*.
