Perhaps you should try some spelling variations:
"destruction technologies" » "construction technologies", "detection technologies", "extraction technologies"
"disruption technologies" » "disruptive technologies", "encryption technologies", "dispersion technologies"
"disruptive technologien" » "disruptive technologies", "disruptive technology", "assistive technologien"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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