• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky tang hoc hoi. hieu ((ve cam) OR (ve chat)) xuc ban thanh nam ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky tang hoc hoi. hieu ((ve cam) or (ve chat)) xuc ban thanh nam ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: vu sach ky tang hoc hoi. hieu ((ve cam) or (ve chat)) xuc ban thanh nam ((cua triet) OR (su triet))*.
