• If you are trying to use Boolean operators, they must be ALL CAPS: (("foreign intelligence surveillance cameras") OR ((("design intelligent surveillance camera") OR ("design intelligent surface camera"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"foreign intelligence surveillance cameras\") or (((\"design intelligent surveillance camera\") OR (\"design intelligent surface camera\"))))*".
• Removing quotes may allow a broader search: (( foreign intelligence surveillance cameras ) or ((( design intelligent surveillance camera ) OR ( design intelligent surface camera ))))*.
