• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. hieu van ((bac tuc) OR (bach tuoc)) ((va doanh) or (va danh)) van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu van ((bac tuc) OR (bach tuoc)) ((va doanh) OR (va danh)) van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu van ((bac tuc) OR (bach tuoc)) ((va doanh) or (va danh)) van cua tre*".
