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