• Performing a fuzzy search may retrieve terms with similar spellings: (("kkanti colony optimization algorithm") OR ("ant colony optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"kkanti colony optimization algorithm\") OR (\"ant colony optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( kkanti colony optimization algorithm ) OR ( ant colony optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("kkanti colony optimization algorithm") OR ("ant colony optimisation algorithm"))*.
