Perhaps you should try some spelling variations:
masse transform » mass transfer, cosine transform
make transform » make transport, can transform, we transform
guia we » guia de, guias de
guide a » guide _
a masse » a mass, b masse, a massive
pairs 3 » pairs _, fairs 3, pairs 1
pairs 4 » pairs _, papers 4

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: (( guia we make transform _ a ) OR ( guide a masse transform ((pairs 3) OR (pairs 4)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guia we make transform _ a ) or ( guide a masse transform ((pairs 3) OR (pairs 4)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( guia we make transform _ a ) or ( guide a masse transform ((pairs 3) OR (pairs 4)) ))*.
