• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach le) OR (cach le)) hang ca hoi. hieu va cam ((xuc va) or (luc va)) danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach le) OR (cach le)) hang ca hoi. hieu va cam ((xuc va) OR (luc va)) danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach le) OR (cach le)) hang ca hoi. hieu va cam ((xuc va) or (luc va)) danh vi cua triet*".
