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