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