• If you are trying to use Boolean operators, they must be ALL CAPS: wai yan yi juan rene ((((yuan ting) OR (huang ting))) OR (tuan minh)) cong sun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan yi juan rene ((((yuan ting) OR (huang ting))) or (tuan minh)) cong sun ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan yi juan rene ((((yuan ting) OR (huang ting))) or (tuan minh)) cong sun ;*.
