Talvez debería tentar con algunhas variantes ortográficas:
international convention » international cooperation, international context, international communication
convention data » conventional data, conversion data, convention hall
data decision » a decision
decision ex » decisions ex, decision e, decision exit

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: international convention data decision ex (libris OR xlibris)~.
• Adding a wildcard symbol may retrieve word variants: international convention data decision ex (libris or xlibris)*.
