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