• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) ty nang xa hoi. hieu ve cham duc tan ((hanh lai) or (hanh lam)) chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ty nang xa hoi. hieu ve cham duc tan ((hanh lai) OR (hanh lam)) chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ty nang xa hoi. hieu ve cham duc tan ((hanh lai) or (hanh lam)) chau triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ty nang xa hoi. hieu ve cham duc tan ((hanh lai) or (hanh lam)) chau triet*.
