• Performing a fuzzy search may retrieve terms with similar spellings: te sach sy long ha hoi. hieu ve cac thu vay ((((doanh van) OR (doanh va))) or (doanh ban)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach sy long ha hoi. hieu ve cac thu vay ((((doanh van) OR (doanh va))) OR (doanh ban)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach sy long ha hoi. hieu ve cac thu vay ((((doanh van) OR (doanh va))) or (doanh ban)) cua tre*".
