Perhaps you should try some spelling variations:
"coder implementation and detection problem" » "code implementation and detection problem" (Expand search), "decoder implementation and detection problem" (Expand search), "model implementation and detection problem" (Expand search), "coder implementation of detection problem" (Expand search), "coder implementation and selection problem" (Expand search), "coder implementation and detection program" (Expand search), "coder implementation and prediction problem" (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)

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 implementation and detection problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder implementation and detection problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder implementation and detection problem") OR ("api python python python programming"))*.
