• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("_ corporation technical report series") OR ("_ incorporating technical report series"))) OR ("_ corporation technological report series"))) OR ((("_ operation technical report series") OR ("_ operation technical report server")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"_ corporation technical report series\") OR (\"_ incorporating technical report series\"))) or (\"_ corporation technological report series\"))) or (((\"_ operation technical report series\") or (\"_ operation technical report server\"))))".
• Removing quotes may allow a broader search: (((((( _ corporation technical report series ) OR ( _ incorporating technical report series ))) or ( _ corporation technological report series ))) or ((( _ operation technical report series ) or ( _ operation technical report server )))).
• Adding a wildcard symbol may retrieve word variants: (((((("_ corporation technical report series") OR ("_ incorporating technical report series"))) or ("_ corporation technological report series"))) or ((("_ operation technical report series") or ("_ operation technical report server"))))*.
