• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sanh)) ty ((hang ca) OR (hang va)) hoi. hieu qua cai xuc ban thanh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sanh)) ty ((hang ca) OR (hang va)) hoi. hieu qua cai xuc ban thanh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sanh)) ty ((hang ca) OR (hang va)) hoi. hieu qua cai xuc ban thanh vi cua tu*".
