Perhaps you should try some spelling variations:
"coder coder present in problem" » "coder under present in problem" (Expand search), "coder model present in problem" (Expand search), "coder poder presentes in problem" (Expand search), "coder decoder present in problem" (Expand search), "code code present in problem" (Expand search), "decoder codec present in 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 coder present in problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder present in problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder present in problem") OR ("api python python python programming"))*.
