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