Perhaps you should try some spelling variations:
"coder complexity doi documentation and" » "coder complexity of documentation and" (Expand search), "coder complexity on documentation and" (Expand search), "coder complexity how documentation and" (Expand search), "code complexity doi documentation and" (Expand search), "model complexity doi documentation and" (Expand search), "lower complexity doi documentation and" (Expand search), "coder complexity dc documentation and" (Expand search), "coder complexity dsp documentation and" (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 doi documentation and\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder complexity doi documentation and ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder complexity doi documentation and") OR ("api python python python programming"))*.
