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