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