Talvez debería tentar con algunhas variantes ortográficas:
multidimensional databases » multidimensional data, multidimensional analysis
communication connection » communications connections, communication connecting, communication collections
dimensions database » dimensional database, dimensional databases, decisions database
connection using » connections using, connectivity using, connection getting

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: communication connection using ((dimensions database) OR (multidimensional databases)) under~.
• Adding a wildcard symbol may retrieve word variants: communication connection using ((dimensions database) or (multidimensional databases)) under*.
