• If you are trying to use Boolean operators, they must be ALL CAPS: (((("computer aid design") OR ("computer rapid design"))) OR ("computer aided design")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computer aid design\") OR (\"computer rapid design\"))) or (\"computer aided design\"))".
• Removing quotes may allow a broader search: (((( computer aid design ) OR ( computer rapid design ))) or ( computer aided design )).
• Adding a wildcard symbol may retrieve word variants: (((("computer aid design") OR ("computer rapid design"))) or ("computer aided design"))*.
