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