• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"distributed estimation of coding program\") OR (\"advanced python programming using program\"))~".
• Removing quotes may allow a broader search: (( distributed estimation of coding program ) OR ( advanced python programming using program ))~.
• Adding a wildcard symbol may retrieve word variants: (("distributed estimation of coding program") OR ("advanced python programming using program"))*.
