Perhaps you should try some spelling variations:
transport code » transport mode, transport modes, transport model
case transfers » cash transfers, based transfers, cash transfer's
transport co2 » transport cost, transport can, transport 2.2
transfers 1.2 » transfers 3.2, transfer 3.2, transfer 2.2
la ideas » las ideas, old ideas, _ ideas
guias do » guia do, guias de, guia de
agua la » agudo la
do case » do cash, do care, two case

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: (( agua la ideas ((transport co2) OR (transport code)) _ ) OR ( guias do case transfers 1.2 das ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua la ideas ((transport co2) OR (transport code)) _ ) or ( guias do case transfers 1.2 das ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua la ideas ((transport co2) OR (transport code)) _ ) or ( guias do case transfers 1.2 das ))*.
