• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu van bac xuc va ((((hanh lam) or (dinh lam))) or (thanh lap)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu van bac xuc va ((((hanh lam) OR (dinh lam))) OR (thanh lap)) cua triet.
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu van bac xuc va ((((hanh lam) or (dinh lam))) or (thanh lap)) cua triet*.
