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