Perhaps you should try some spelling variations:
sea transport » road transport, bus transport
cash transfer » cash transfers
transport a » transport _, transport data
resource a » resource _, resource 3, resource b
resource 5 » resource _, resource 2.2
luis de » luis e
de cash » de cas, do cash, de caso
a mark » a markt, a mask, d mark

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: (( luis _ sea transport a mark ) OR ( luis de cash transfer ((resource a) OR (resource 5)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis _ sea transport a mark ) or ( luis de cash transfer ((resource a) OR (resource 5)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis _ sea transport a mark ) or ( luis de cash transfer ((resource a) OR (resource 5)) ))*.
