Perhaps you should try some spelling variations:
"coder coding _ algorithms complexity" » "coder coding _ algorithmic complexity" (Expand search), "modern coding _ algorithms complexity" (Expand search), "color coding _ algorithms complexity" (Expand search), "odor coding _ algorithms complexity" (Expand search)
"api python based python programming" » "api action based python programming" (Expand search), "api python based path programming" (Expand search), "api python and python programming" (Expand search), "api python gate python programming" (Expand search), "rpa python based python programming" (Expand search), "manim python based 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 coding _ algorithms complexity") OR ("api python based python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coding _ algorithms complexity\") OR (\"api python based python programming\"))".
• Removing quotes may allow a broader search: (( coder coding _ algorithms complexity ) OR ( api python based python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coding _ algorithms complexity") OR ("api python based python programming"))*.
