Perhaps you should try some spelling variations:
"coder firefly algorithm with array" » "covq firefly algorithm with array" (Expand search), "coder firefly algorithm with spray" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (Expand search)

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: "((\"coder firefly algorithm with array\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder firefly algorithm with array ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder firefly algorithm with array") OR ("api python python python programming"))*.
