Perhaps you should try some spelling variations:
"coder _ clustering algorithm programming" » "coder _ clustering algorithms programming" (Expand search), "coder _ clustering algorithm processing" (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 _ clustering algorithm programming\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ clustering algorithm programming ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ clustering algorithm programming") OR ("api python python python programming"))*.
