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