• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((ty trang) OR (ta trang)) va hoi. hieu ve cham xuc va ((dang van) or (doanh van)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ty trang) OR (ta trang)) va hoi. hieu ve cham xuc va ((dang van) OR (doanh van)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ty trang) OR (ta trang)) va hoi. hieu ve cham xuc va ((dang van) or (doanh van)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ty trang) OR (ta trang)) va hoi. hieu ve cham xuc va ((dang van) or (doanh van)) cuu tre*.
