• The words AND, OR and NOT may confuse the search; try adding quotes: "long ((((learning tom) OR (learning tony))) or (learning time)) j gao ying jae song hai ;~".
• Adding a wildcard symbol may retrieve word variants: long ((((learning tom) OR (learning tony))) or (learning time)) j gao ying jae song hai ;*.
