• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ly) or (sach lo)) nang mai hoi. hieu ((va cam) OR (va cham)) tuc va manh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ly) OR (sach lo)) nang mai hoi. hieu ((va cam) OR (va cham)) tuc va manh hai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ly) or (sach lo)) nang mai hoi. hieu ((va cam) OR (va cham)) tuc va manh hai cau treo*".
