• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ty) or (sach thu)) dang van hoc. thien van lam xuc ((va hanh) OR (va thanh)) de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ty) OR (sach thu)) dang van hoc. thien van lam xuc ((va hanh) OR (va thanh)) de cua triet.
