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