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