• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((quang cu) or (quang cua)) hoi. hieu va coc ((luc va) OR (duc va)) danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((quang cu) OR (quang cua)) hoi. hieu va coc ((luc va) OR (duc va)) danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((quang cu) or (quang cua)) hoi. hieu va coc ((luc va) OR (duc va)) danh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((quang cu) or (quang cua)) hoi. hieu va coc ((luc va) OR (duc va)) danh vi cua triet*.
