• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((sang tao) or (nang ma)) hoi. hieu ve cham tuc va dan ((vi cuu) OR (vinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((sang tao) OR (nang ma)) hoi. hieu ve cham tuc va dan ((vi cuu) OR (vinh cuu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((sang tao) or (nang ma)) hoi. hieu ve cham tuc va dan ((vi cuu) OR (vinh cuu)) tre".
