• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach thu mua gioi cong thong tin ) OR ( su sach ((nha me) OR (nha xe)) gioi co hoang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach thu mua gioi cong thong tin ) or ( su sach ((nha me) OR (nha xe)) gioi co hoang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach thu mua gioi cong thong tin ) or ( su sach ((nha me) OR (nha xe)) gioi co hoang minh ))*.
