• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((cha ve) OR (cha va)) giai cam hoang minh ) OR ( tu sach cha me giai han hoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((cha ve) or (cha va)) giai cam hoang minh ) or ( tu sach cha me giai han hoang minh ))*.
