• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang xa hoi. hieu ((ve cham) OR (vu cham)) luc ((va lanh) OR (va hanh)) dao cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang xa hoi. hieu ((ve cham) OR (vu cham)) luc ((va lanh) or (va hanh)) dao cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y tang xa hoi. hieu ((ve cham) OR (vu cham)) luc ((va lanh) or (va hanh)) dao cua triet*.
