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