Talvez debería tentar con algunhas variantes ortográficas:
conversion basic » conversation basic, conversion based, convection basic
collision based » collocation based, collision system, collision cables
cohesion based » conversion based, corrosion based, lesion based
dimensions 4.1 » dimensions 3.3, dimensions 9.5, dimensions 10.2

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication ((conversion basic) or (((cohesion based) OR (collision based)))) dimensions 4.1 live~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication ((conversion basic) OR (((cohesion based) OR (collision based)))) dimensions 4.1 live.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication ((conversion basic) or (((cohesion based) OR (collision based)))) dimensions 4.1 live".
• Adding a wildcard symbol may retrieve word variants: communication ((conversion basic) or (((cohesion based) OR (collision based)))) dimensions 4.1 live*.
