• Performing a fuzzy search may retrieve terms with similar spellings: tu cach tu hang ca hoi. hieu va cam ((duc phan) or (suc manh)) ((hanh lam) OR (hanh kem)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach tu hang ca hoi. hieu va cam ((duc phan) OR (suc manh)) ((hanh lam) OR (hanh kem)) cua triet.
