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