Perhaps you should try some spelling variations:
"coder complexity metrics coding program" » "code complexity metrics coding program" (Expand search), "model complexity metrics coding program" (Expand search), "lower complexity metrics coding program" (Expand search), "coder complexity metrics using program" (Expand search), "coder complexity metrics code program" (Expand search), "coder complexity metrics including program" (Expand search), "coder complexity metrics cloning program" (Expand search), "coder complexity metrics loading program" (Expand search), "coder complexity metrics cooling programs" (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 complexity metrics coding program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder complexity metrics coding program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder complexity metrics coding program") OR ("api python python python programming"))*.
