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