• Performing a fuzzy search may retrieve terms with similar spellings: ho ((thiet quan) OR (thuat quan)) - anh tang ((va nang) or (va lang)) cong ban thanh cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((thiet quan) OR (thuat quan)) - anh tang ((va nang) OR (va lang)) cong ban thanh cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((thiet quan) OR (thuat quan)) - anh tang ((va nang) or (va lang)) cong ban thanh cap*".
