• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tai lang xa hoi. hieu ((va cao) or (va cham)) ((trung va) OR (truong va)) hanh lam su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tai lang xa hoi. hieu ((va cao) OR (va cham)) ((trung va) OR (truong va)) hanh lam su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tai lang xa hoi. hieu ((va cao) or (va cham)) ((trung va) OR (truong va)) hanh lam su triet".
• Adding a wildcard symbol may retrieve word variants: tu sach tai lang xa hoi. hieu ((va cao) or (va cham)) ((trung va) OR (truong va)) hanh lam su triet*.
