Perhaps you should try some spelling variations:
transport signal » transform signal, transport design, transport annual
based transfers » basin transfers, cash transfers, land transfers
transfers 6 » transfers _, transfers 3, transfers 2
own ideas » old ideas
guias ode » guias de, guia de
ode based » code based, mode based, diode based
signal 4 » signal _, signal 3, signal 6
6 can » _ can, 3 can, 4 can
aguas » agus, agua

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 ((own ideas) OR (two ideas)) transport signal 4 ) OR ( guias ode based transfers 6 can ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas ((own ideas) OR (two ideas)) transport signal 4 ) or ( guias ode based transfers 6 can ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas ((own ideas) OR (two ideas)) transport signal 4 ) or ( guias ode based transfers 6 can ))*.
