Perhaps you should try some spelling variations:
"coder code in authentication protocol" » "coder code wine authentication protocol" (Expand search), "coder code and authentication protocol" (Expand search), "coder code _ authentication protocol" (Expand search), "code code in authentication protocol" (Expand search), "modern code in authentication protocol" (Expand search), "color code in authentication protocol" (Expand search)
"in python python python programming" » "in pythons python python programming" (Expand search), "in piton python python programming" (Expand search), "in pitons python python programming" (Expand search), "_ 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 in authentication protocol\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code in authentication protocol ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code in authentication protocol") OR ("in python python python programming"))*.
