• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y ((sang ma) or (sang tao)) hoi. lieu va tham loc va danh ((vai cua) OR (hai cua)) tre~.
• 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 loc va danh ((vai cua) OR (hai cua)) tre.
• 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 loc va danh ((vai cua) OR (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((sang ma) or (sang tao)) hoi. lieu va tham loc va danh ((vai cua) OR (hai cua)) tre*.
