Perhaps you should try some spelling variations:
"and computational coder location problem" » "and computational code location problem" (Expand search), "and computational codes location problem" (Expand search), "and computational model location problem" (Expand search), "_ computational coder location problem" (Expand search), "and computational over location problem" (Expand search), "and computational under location problem" (Expand search)
"learning python python python programming" » "learning paths python python programming" (Expand search), "learning path python python programming" (Expand search), "learning pythons python python programming" (Expand search), "learning piton python python programming" (Expand search), "learning pitons python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("and computational coder location problem") OR ("learning python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational coder location problem\") OR (\"learning python python python programming\"))*".
• Removing quotes may allow a broader search: (( and computational coder location problem ) OR ( learning python python python programming ))*.
