• If you are trying to use Boolean operators, they must be ALL CAPS: (( vu sach han me gioi bon hoang minh ) OR ( thu sach ha ((me giai) OR (ve giai)) han thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vu sach han me gioi bon hoang minh ) or ( thu sach ha ((me giai) OR (ve giai)) han thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( vu sach han me gioi bon hoang minh ) or ( thu sach ha ((me giai) OR (ve giai)) han thong tin ))*.
