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