• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced oxidation of coding program\") OR (\"based optimization by python programming\"))".
• Removing quotes may allow a broader search: (( advanced oxidation of coding program ) OR ( based optimization by python programming )).
• Adding a wildcard symbol may retrieve word variants: (("advanced oxidation of coding program") OR ("based optimization by python programming"))*.
