Perhaps you should try some spelling variations:
transport en » transport et, transport can, transport _
transfer sur » transfer der, transfer auf, transfer aus
guias case » grids case
case heat » case heart, case health, waste heat
en costa » can costa, en contra, _ costa
de bus » de boues, de busca
sur a » sur la, sgr a, sul a

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: (( guias case heat transfer sur a ) OR ( guia de bus transport en costa ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias case heat transfer sur a ) or ( guia de bus transport en costa ))*.
