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