• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using complexed with coding program\") OR (\"using integration theory housing program\"))*".
• Removing quotes may allow a broader search: (( using complexed with coding program ) OR ( using integration theory housing program ))*.
