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