Perhaps you should try some spelling variations:
"coder using coefficient in program" » "coder using efficient in program" (Expand search), "coder gini coefficient in program" (Expand search), "coder coupling coefficient in program" (Expand search), "coder using coefficient of program" (Expand search), "coders using coefficient in program" (Expand search), "cover using coefficient in program" (Expand search), "code using coefficient in program" (Expand search), "coder using coefficient in programs" (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 using coefficient in program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder using coefficient in program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder using coefficient in program") OR ("api python python python programming"))*.
