Talvez debería tentar con algunhas variantes ortográficas:
instruction comprehensive » introduction comprehensive, introduction comprehension, constructive comprehension
programming elements » programme elements, programming environments, programming projects
programming errors » programming effort, programming reactors, programming entropy
concepts care » concepts case, concepts cases, concepts karen

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: instruction comprehensive ((programming errors) OR (programming elements)) concepts care~.
• Adding a wildcard symbol may retrieve word variants: instruction comprehensive ((programming errors) or (programming elements)) concepts care*.
