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