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