• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ly vang x hoi. hieu ((ve cau) or (va cau)) truc ((va doanh) OR (van doanh)) van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ly vang x hoi. hieu ((ve cau) OR (va cau)) truc ((va doanh) OR (van doanh)) van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ly vang x hoi. hieu ((ve cau) or (va cau)) truc ((va doanh) OR (van doanh)) van cua tre*".
