• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty lang) OR (ty hang)) xa hoi. thien van nam duc va hang le ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty lang) or (ty hang)) xa hoi. thien van nam duc va hang le ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty lang) or (ty hang)) xa hoi. thien van nam duc va hang le ((cua te) OR (cua tu))*.
