• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ty) OR (sach y)) ((hoang van) or (tang van)) hoi. hieu van lam xuc va hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ty) OR (sach y)) ((hoang van) OR (tang van)) hoi. hieu van lam xuc va hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ty) OR (sach y)) ((hoang van) or (tang van)) hoi. hieu van lam xuc va hanh vi cua triet*".
