• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky tang van hoa. ((((hieu ve) OR (hieu van))) or (hieu va)) cam duc van hanh dinh cu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang van hoa. ((((hieu ve) OR (hieu van))) OR (hieu va)) cam duc van hanh dinh cu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang van hoa. ((((hieu ve) OR (hieu van))) or (hieu va)) cam duc van hanh dinh cu tre*".
