Perhaps you should try some spelling variations:
"coder and coverage cognitive function" » "coder and average cognitive function" (Expand search), "coder and cooperative cognitive function" (Expand search), "coder and coverage cognitive dysfunction" (Expand search), "coder and cover cognitive function" (Expand search), "code and coverage cognitive function" (Expand search), "codes and coverage cognitive function" (Expand search), "poder and coverage cognitive function" (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 and coverage cognitive function\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder and coverage cognitive function ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder and coverage cognitive function") OR ("in python python python programming"))*.
