Perhaps you should try some spelling variations:
"coder coder _ challenges from" » "coder coder _ challenges of" (Expand search), "coder coder _ challenges on" (Expand search), "coder coder _ challenges faced" (Expand search), "coder decoder _ challenges from" (Expand search), "code code _ challenges from" (Expand search), "decoder codec _ challenges from" (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 coder _ challenges from\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder _ challenges from ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder _ challenges from") OR ("api python python python programming"))*.
