transport plan » transport planning, transport policy
transfer em » transfer beim, transfer der, transfer fee
debt heat » debt great, debt debt
debt has » debt cash, debt a, debt how
mcao » macao, mao, miao

• Performing a fuzzy search may retrieve terms with similar spellings: (( u.s ((debt heat) OR (debt has)) transfer em cao ) or ( luis _ local transport plan mcao ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( u.s ((debt heat) OR (debt has)) transfer em cao ) OR ( luis _ local transport plan mcao ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( u.s ((debt heat) OR (debt has)) transfer em cao ) or ( luis _ local transport plan mcao ))*".
