• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach lo) or (sach y)) nang ma hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach lo) OR (sach y)) nang ma hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach lo) or (sach y)) nang ma hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) te*".
