• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang xa hoi. hieu ((ve cham) OR (ve chat)) luc ((va hang) OR (va nang)) tai 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 (ve chat)) luc ((va hang) OR (va nang)) tai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y tang xa hoi. hieu ((ve cham) or (ve chat)) luc ((va hang) OR (va nang)) tai cua triet*.
