• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (((sach ty) OR (sach y)))) nang xa hoi. hieu ve cac lo ban thanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (((sach ty) OR (sach y)))) nang xa hoi. hieu ve cac lo ban thanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (((sach ty) OR (sach y)))) nang xa hoi. hieu ve cac lo ban thanh di cua triet*".
