Perhaps you should try some spelling variations:
"coder code complexity abc program" » "coder case complexity abc program" (Expand search), "coder the complexity abc program" (Expand search), "coder and complexity abc program" (Expand search), "coder code complexity and program" (Expand search), "coder code complexity an program" (Expand search), "coder code complexity at program" (Expand search), "code code complexity abc program" (Expand search), "modern code complexity abc program" (Expand search), "color code complexity abc program" (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 code complexity abc program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code complexity abc program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code complexity abc program") OR ("api python python python programming"))*.
