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