You may be able to get more results by adjusting your search query.

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