• The words AND, OR and NOT may confuse the search; try adding quotes: "(( compra python code ore processing ) OR ( using rotating system python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( compra python code ore processing ) OR ( using rotating system python programming ))*.
