• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang learning) OR (sharing learning)) tony h gao ying ((ji shang) OR (xia shang)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang learning) or (sharing learning)) tony h gao ying ((ji shang) OR (xia shang)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang learning) or (sharing learning)) tony h gao ying ((ji shang) OR (xia shang)) hai ;*.
