• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chiet tach) or (((chieu sang) OR (hieu lang)))) - thanh tung ve nhung cong dan chan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (((chieu sang) OR (hieu lang)))) - thanh tung ve nhung cong dan chan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (((chieu sang) OR (hieu lang)))) - thanh tung ve nhung cong dan chan cau*".
