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