Talvez debería tentar con algunhas variantes ortográficas:
communication mass » communication models, communication making, communication media
mass extension » rams extension, rss extension, basins extension
array paving » array planning, array imaging, array probing
array along » array arcing, array strong
arrays long » arrays ang, arrays load, arrays lens

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 communication mass extension ((((array along) OR (arrays long))) OR (array paving))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication communication mass extension ((((array along) OR (arrays long))) or (array paving))~".
• Adding a wildcard symbol may retrieve word variants: communication communication mass extension ((((array along) OR (arrays long))) or (array paving))*.
