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