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