Perhaps you should try some spelling variations:
"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)
"coder java xgboost algorithm in" » "coder and xgboost algorithm in" (Expand search), "coder java xgboost algorithm and" (Expand search), "coder java xgboost algorithm _" (Expand search), "coder java xgboost algorithm with" (Expand search), "codes java xgboost algorithm in" (Expand search), "xcode java xgboost algorithm in" (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 java xgboost algorithm in\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder java xgboost algorithm in ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder java xgboost algorithm in") OR ("api python python python programming"))*.
