• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decrease costa processo ) OR ( function based pattern python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease costa processo ) OR ( function based pattern python programming ))*.
