• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ((cha ve) OR (ca ve)) gioi co hoang minh ) OR ( thuat san kha ke nguoi co hoang minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ((cha ve) OR (ca ve)) gioi co hoang minh ) or ( thuat san kha ke nguoi co hoang minh ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ((cha ve) OR (ca ve)) gioi co hoang minh ) or ( thuat san kha ke nguoi co hoang minh ))*.
