• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((ha le) OR (va le)) nguoi tran quang minh ) OR ( thu sach mai ma gioi bon hong minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((ha le) OR (va le)) nguoi tran quang minh ) or ( thu sach mai ma gioi bon hong minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((ha le) OR (va le)) nguoi tran quang minh ) or ( thu sach mai ma gioi bon hong minh ))*.
