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