Perhaps you should try some spelling variations:
transfers have » transfers made
und transport » land transport, road transport, good transport
gua trade » a trade, tea trade, guinea trade
era trade » a trade, tea trade
costs ch » costs cash, costs chap, costs _
have any » have a, have all
aguas a » aguas de, aguas do

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: (( ((gua trade) OR (era trade)) und transport costs ch ) OR ( aguas a fiscal transfers have any ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((gua trade) OR (era trade)) und transport costs ch ) or ( aguas a fiscal transfers have any ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((gua trade) OR (era trade)) und transport costs ch ) or ( aguas a fiscal transfers have any ))*.
