Perhaps you should try some spelling variations:
"coder and constraints on programmer" » "coder and constraints on programmed" (Expand search), "coder and constraints non programmers" (Expand search), "coder and constraints of programmers" (Expand search), "code and constraints on programmer" (Expand search), "codes and constraints on programmer" (Expand search), "poder and constraints on programmer" (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 and constraints on programmer\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder and constraints on programmer ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder and constraints on programmer") OR ("api python python python programming"))*.
