• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang mai hoi. hieu ve cam ((xuc gia) or (duc gia)) thanh ((van cua) OR (ban cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang mai hoi. hieu ve cam ((xuc gia) OR (duc gia)) thanh ((van cua) OR (ban cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang mai hoi. hieu ve cam ((xuc gia) or (duc gia)) thanh ((van cua) OR (ban cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang mai hoi. hieu ve cam ((xuc gia) or (duc gia)) thanh ((van cua) OR (ban cua)) triet*.
