Perhaps you should try some spelling variations:
"coder approximation algorithm learning objects" » "coder approximation algorithms learning objects" (Expand search), "power approximation algorithm learning objects" (Expand search), "order approximation algorithm learning objects" (Expand search), "model approximation algorithm learning objects" (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 approximation algorithm learning objects") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder approximation algorithm learning objects\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder approximation algorithm learning objects ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder approximation algorithm learning objects") OR ("api python python python programming"))*.
