Perhaps you should try some spelling variations:
"computer aimed design" » "computer aided design", "computer aid design", "computer aide design", "computer timed design", "computer timed designs"
"computer added design" » "computer aided design", "computer guided design", "computer age design", "computer added designs", "computer adder design"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"computer aimed design\") OR (\"computer added design\"))*".
• Removing quotes may allow a broader search: (( computer aimed design ) OR ( computer added design ))*.
