• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((ky tang) OR (ky dang)) ma hoa. hieu ((ve cam) or (ve cham)) xuc va dinh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky tang) OR (ky dang)) ma hoa. hieu ((ve cam) OR (ve cham)) xuc va dinh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky tang) OR (ky dang)) ma hoa. hieu ((ve cam) or (ve cham)) xuc va dinh vi cua te*".
