• Performing a fuzzy search may retrieve terms with similar spellings: tu sach vu sang ((ma hoi) OR (mai hoi)). hieu ((ve cam) or (va cam)) xuc va hanh hai cau trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach vu sang ((ma hoi) OR (mai hoi)). hieu ((ve cam) OR (va cam)) xuc va hanh hai cau trieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach vu sang ((ma hoi) OR (mai hoi)). hieu ((ve cam) or (va cam)) xuc va hanh hai cau trieu".
• Adding a wildcard symbol may retrieve word variants: tu sach vu sang ((ma hoi) OR (mai hoi)). hieu ((ve cam) or (va cam)) xuc va hanh hai cau trieu*.
