Perhaps you should try some spelling variations:
"coder implementation _ checking programmer" » "code implementation _ checking programmer" (Expand search), "decoder implementation _ checking programmer" (Expand search), "model implementation _ checking programmer" (Expand search), "coder implementation _ screening programmes" (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 implementation _ checking programmer\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder implementation _ checking programmer ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder implementation _ checking programmer") OR ("api python python python programming"))*.
