• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky dang lap hai. hieu ve cam ((luc va) or (((loc va) OR (hoc va)))) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang lap hai. hieu ve cam ((luc va) OR (((loc va) OR (hoc va)))) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang lap hai. hieu ve cam ((luc va) or (((loc va) OR (hoc va)))) hanh vi cua te*".
