Perhaps you should try some spelling variations:
"computer-guided engineering" » "computer-guide toengineering", "computer-grid engineering", "computer-build engineering"
"computer-added engineering" » "computer-radder engineering", "computer-valued engineering", "computer-based engineering"
"computer-aided engineering" » "computer-aimed engineering"

Try widening your search to All Fields.

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: (((("computer-aided engineering") OR ("computer-guided engineering"))) OR ("computer-added engineering")).
• Removing quotes may allow a broader search: (((( computer-aided engineering ) or ( computer-guided engineering ))) or ( computer-added engineering )).
• Adding a wildcard symbol may retrieve word variants: (((("computer-aided engineering") or ("computer-guided engineering"))) or ("computer-added engineering"))*.
