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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"uses interference\") OR (\"used interference\"))) OR (\"use interference\"))~".
• Removing quotes may allow a broader search: (((( uses interference ) OR ( used interference ))) OR ( use interference ))~.
• Adding a wildcard symbol may retrieve word variants: (((("uses interference") OR ("used interference"))) OR ("use interference"))*.
