• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ky dang lai hoi. ((hieu su) or (tieu su)) chat ((xuc va) OR (duc va)) hanh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky dang lai hoi. ((hieu su) OR (tieu su)) chat ((xuc va) OR (duc va)) hanh va cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky dang lai hoi. ((hieu su) or (tieu su)) chat ((xuc va) OR (duc va)) hanh va cua te".
