Perhaps you should try some spelling variations:
"coder _ computational coding problems" » "coder _ computational modeling problems" (Expand search), "coder _ computational docking problems" (Expand search), "coder _ computational code problems" (Expand search), "coder _ computational loading problems" (Expand search), "coder _ computational counting problems" (Expand search), "coder _ computational covering problems" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder _ computational coding problems") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder _ computational coding problems\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder _ computational coding problems ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder _ computational coding problems") OR ("api python python python programming"))*.
