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