• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - canh tranh ((((cua trong) OR (qua trong))) OR (cua trung)) cong pham tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - canh tranh ((((cua trong) OR (qua trong))) or (cua trung)) cong pham tuan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - canh tranh ((((cua trong) OR (qua trong))) or (cua trung)) cong pham tuan ban*.
