• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"weber von siemens fing\") OR (\"wieder von siemens fing\"))) OR (\"werner von siemens ging\"))~".
• Removing quotes may allow a broader search: (((( weber von siemens fing ) OR ( wieder von siemens fing ))) OR ( werner von siemens ging ))~.
• Adding a wildcard symbol may retrieve word variants: (((("weber von siemens fing") OR ("wieder von siemens fing"))) OR ("werner von siemens ging"))*.
