Perhaps you should try some spelling variations:
des transfers » net transfers, cash transfers, arms transfers
transfers ai » transfers i, transfers bei, transfers dau
transfer em » transfer beim, transfer der, transfer fee
aguas del » aguas de
aguas do » aguas de
guide e » guide de, guide et, guide _
e heat » _ heat, a heat, 1 heat

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((aguas do) OR (aguas del)) des transfers ai cao ) OR ( guide e heat transfer em cham ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((aguas do) OR (aguas del)) des transfers ai cao ) or ( guide e heat transfer em cham ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((aguas do) OR (aguas del)) des transfers ai cao ) or ( guide e heat transfer em cham ))*.
