• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - hanh trinh cua nhung song van ((han tap) OR (han tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - hanh trinh cua nhung song van ((han tap) OR (han tai))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - hanh trinh cua nhung song van ((han tap) OR (han tai))*.
