• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((sang ma) or (sang tao)) hoi. lieu va ((tham luc) OR (tham nuoc)) va danh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((sang ma) OR (sang tao)) hoi. lieu va ((tham luc) OR (tham nuoc)) va danh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((sang ma) or (sang tao)) hoi. lieu va ((tham luc) OR (tham nuoc)) va danh vai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((sang ma) or (sang tao)) hoi. lieu va ((tham luc) OR (tham nuoc)) va danh vai cua te*.
