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