• If you are trying to use Boolean operators, they must be ALL CAPS: (((("word devices technical paper") OR ("word devices electrical paper"))) OR ("work ai technical papers"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"word devices technical paper\") OR (\"word devices electrical paper\"))) or (\"work ai technical papers\"))*".
• Removing quotes may allow a broader search: (((( word devices technical paper ) OR ( word devices electrical paper ))) or ( work ai technical papers ))*.
