• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y nang xa hoi. hieu ve ((cho xu) OR (cho du)) ((va kinh) or (van dinh)) va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ve ((cho xu) OR (cho du)) ((va kinh) OR (van dinh)) va cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ve ((cho xu) OR (cho du)) ((va kinh) or (van dinh)) va cua te*".
