• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((yuan yan) OR (yuan yuan)) hui ji shi tian wen da xi. ) OR ( guan hua hui de di san wen da xi. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((yuan yan) OR (yuan yuan)) hui ji shi tian wen da xi. ) or ( guan hua hui de di san wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((yuan yan) OR (yuan yuan)) hui ji shi tian wen da xi. ) or ( guan hua hui de di san wen da xi. ))*.
