Perhaps you should try some spelling variations:
"coder functional complexity and problem" » "coder functional complex and problem" (Expand search), "coder functional composite and problem" (Expand search), "coder relational complexity and problem" (Expand search), "modern functional complexity and problem" (Expand search), "border functional complexity and problem" (Expand search), "order functional complexity and problem" (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 functional complexity and problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder functional complexity and problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder functional complexity and problem") OR ("api python python python programming"))*.
