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