Perhaps you should try some spelling variations:
"coder string machine algorithms complexity" » "coder string machine algorithmic complexity" (Expand search), "coder string machine algorithm complexity" (Expand search), "coder string matching algorithms complexity" (Expand search), "coder string caching algorithms complexity" (Expand search), "coder suturing machine algorithms complexity" (Expand search), "coder scoring machine algorithms complexity" (Expand search), "cordel string machine algorithms complexity" (Expand search), "closed string machine algorithms complexity" (Expand search), "modelo string machine algorithms 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 string machine algorithms complexity") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder string machine algorithms complexity\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder string machine algorithms complexity ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder string machine algorithms complexity") OR ("api python python python programming"))*.
