Perhaps you should try some spelling variations:
"computer aimed design" » "computer aided design", "computer aid design", "computer added design", "computer timed designs", "computer mixed design"
"computer timed design" » "computer time design", "compute time design", "computers time design", "computer timed designs", "computer timer 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 timed design\"))".
• Removing quotes may allow a broader search: (( computer aimed design ) OR ( computer timed design )).
• Adding a wildcard symbol may retrieve word variants: (("computer aimed design") OR ("computer timed design"))*.
