Perhaps you should try some spelling variations:
"coder application python arduino protected" » "coder application method arduino protected" (Expand search), "coder aplicativo python arduino protected" (Expand search), "coder application methods arduino protected" (Expand search), "code application python arduino protected" (Expand search), "codes application python arduino protected" (Expand search), "copper application python arduino protected" (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 application python arduino protected\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder application python arduino protected ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder application python arduino protected") OR ("api python python python programming"))*.
