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 in python programming" » "rpa python in python programming" (Expand search), "manim python in python programming" (Expand search), "api python and python programming" (Expand search), "api python _ python programming" (Expand search), "api python c python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coding _ algorithms complexity\") OR (\"api python in python programming\"))~".
• Removing quotes may allow a broader search: (( coder coding _ algorithms complexity ) OR ( api python in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coding _ algorithms complexity") OR ("api python in python programming"))*.
