• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky ((tang ma) OR (mang may)) hoa. hieu ((ve cham) or (va cham)) xuc van minh tri 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 cham) OR (va cham)) xuc van minh tri 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 cham) or (va cham)) xuc van minh tri cua te*".
