Perhaps you should try some spelling variations:
"coder _ programming algorithms estimation" » "coder _ programming algorithm estimation" (Expand search), "coder _ processing algorithms estimation" (Expand search), "coder _ programming algorithms optimization" (Expand search), "coder _ programming algorithms simulation" (Expand search), "coder _ programming algorithms evaluation" (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 _ programming algorithms estimation") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder _ programming algorithms estimation\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder _ programming algorithms estimation ) OR ( api python python python programming ))*.
