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