• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"of convolutional drying using program\") OR (\"advanced functionality in python programming\"))~".
• Removing quotes may allow a broader search: (( of convolutional drying using program ) OR ( advanced functionality in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("of convolutional drying using program") OR ("advanced functionality in python programming"))*.
