Perhaps you should try some spelling variations:
"coder field approximation algorithm based" » "coder field approximation algorithms based" (Expand search), "coder field approximation algorithm and" (Expand search), "cover field approximation algorithm based" (Expand search), "under field approximation algorithm based" (Expand search), "power field approximation algorithm based" (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 field approximation algorithm based") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder field approximation algorithm based\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder field approximation algorithm based ) OR ( api python python python programming ))*.
