• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thieu lang xa hoi. thi hanh cam ((((xuc va) OR (luc va))) or (thuc va)) hanh lam chay tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thieu lang xa hoi. thi hanh cam ((((xuc va) OR (luc va))) OR (thuc va)) hanh lam chay tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thieu lang xa hoi. thi hanh cam ((((xuc va) OR (luc va))) or (thuc va)) hanh lam chay tren".
• Adding a wildcard symbol may retrieve word variants: tu sach thieu lang xa hoi. thi hanh cam ((((xuc va) OR (luc va))) or (thuc va)) hanh lam chay tren*.
