• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky ((nang cao) or (dang van)) hoi. hieu va cam ((xuc van) OR (duc van)) anh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky ((nang cao) OR (dang van)) hoi. hieu va cam ((xuc van) OR (duc van)) anh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky ((nang cao) or (dang van)) hoi. hieu va cam ((xuc van) OR (duc van)) anh vi cua triet*".
