• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((anh dang) OR (anh bang)) cua nhung cong tan ((toan ban) OR (ban cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((anh dang) OR (anh bang)) cua nhung cong tan ((toan ban) or (ban cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((anh dang) OR (anh bang)) cua nhung cong tan ((toan ban) or (ban cau))*.
