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