Perhaps you should try some spelling variations:
"coder code based sample problem" » "coder code based complex problem" (Expand search), "coder code based same problems" (Expand search), "coder code and sample problem" (Expand search), "code code based sample problem" (Expand search), "modern code based sample problem" (Expand search), "color code based sample problem" (Expand search), "coder case based sample 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 code based sample problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code based sample problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code based sample problem") OR ("api python python python programming"))*.
