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