Talvez debería tentar con algunhas variantes ortográficas:
multidimensional databases » multidimensional data, multidimensional analysis
communication adhesion » communication cohesion, communication aggression, communication affection
dimensional datasets » dimensional data, dimensional case
adhesion all » adhesion cell, adhesion a, adhesions cell

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 adhesion all ((multidimensional databases) OR (dimensional datasets)) optimising~.
• Adding a wildcard symbol may retrieve word variants: communication adhesion all ((multidimensional databases) or (dimensional datasets)) optimising*.
