• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sach tham)) nang xa hoi. hieu van hac xuc va ((hanh lam) OR (thanh hai)) cua triet.
• Adding a wildcard symbol may retrieve word variants: tu ((sach y) or (sach tham)) nang xa hoi. hieu van hac xuc va ((hanh lam) or (thanh hai)) cua triet*.
