Perhaps you should try some spelling variations:
gases transfer » mass transfer, based transfer, gas transfer
transform a » transform _, transform our, transform 2.4
transfer 3 » transfer _, transfer 4, transfer a
own ideas » two ideas
old ideas » good ideas
guias de » guia de, guide de, aguas de
de gases » de bases, _ gases, f gases
3 ao » 3 a, 3 co, 3 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: (( areas ((own ideas) OR (old ideas)) transform a 4 ) OR ( guias de gases transfer 3 ao ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas ((own ideas) or (old ideas)) transform a 4 ) or ( guias de gases transfer 3 ao ))*.
