• If you are trying to use Boolean operators, they must be ALL CAPS: long ((((learning tom) OR (learning tim))) OR (learning time)) j gao ying jae song hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long ((((learning tom) OR (learning tim))) or (learning time)) j gao ying jae song hai ;~".
• Adding a wildcard symbol may retrieve word variants: long ((((learning tom) OR (learning tim))) or (learning time)) j gao ying jae song hai ;*.
