• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (te sach))) OR (thu sach)) ky dang xa hoi. hieu ve cham loc va danh vu va triet~.
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) or (te sach))) or (thu sach)) ky dang xa hoi. hieu ve cham loc va danh vu va triet*.
