• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ca ve cao cong trong kinh ) OR ( thu sach ((cha ve) OR (cha me)) gia cong hoang minh ))~.
• Adding a wildcard symbol may retrieve word variants: (( te sach ca ve cao cong trong kinh ) or ( thu sach ((cha ve) or (cha me)) gia cong hoang minh ))*.
