• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (doc hieu)) sang - hanh trinh cua ((nhung don) OR (thong cong)) tan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (doc hieu)) sang - hanh trinh cua ((nhung don) or (thong cong)) tan than cao~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (doc hieu)) sang - hanh trinh cua ((nhung don) or (thong cong)) tan than cao*.
