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