Perhaps you should try some spelling variations:
"coder using fft algorithm complexity" » "coder using fft algorithms complexity" (Expand search), "coder using fft algorithmic complexity" (Expand search), "coder using fast algorithm complexity" (Expand search), "coder using bat algorithm complexity" (Expand search), "coder using cut algorithm complexity" (Expand search), "coders using fft algorithm complexity" (Expand search), "cover using fft algorithm complexity" (Expand search), "code using fft algorithm complexity" (Expand search), "coder using fmt algorithm complexity" (Expand search), "coder using fdtd algorithm complexity" (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), "manim 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 using fft algorithm complexity") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder using fft algorithm complexity\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder using fft algorithm complexity ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder using fft algorithm complexity") OR ("api python python python programming"))*.
