Perhaps you should try some spelling variations:
"coder code and duplicated coverage" » "coder code and duplicate coverage" (Expand search), "coder code and implicated coverage" (Expand search), "coder code and replicated coverage" (Expand search), "code code and duplicated coverage" (Expand search), "modern code and duplicated coverage" (Expand search), "color code and duplicated coverage" (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 and duplicated coverage\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code and duplicated coverage ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code and duplicated coverage") OR ("in python python python programming"))*.
