Perhaps you should try some spelling variations:
"coder computational coder execution time" » "code computational coder execution time" (Expand search), "poder computacional coder execution time" (Expand search), "model computational coder execution time" (Expand search), "coder computational code execution time" (Expand search), "coder computational codes execution time" (Expand search), "coder computational model execution time" (Expand search), "coder computational over execution time" (Expand search)
"_ python python python programming" » "_ pythons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ 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: (("coder computational coder execution time") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder computational coder execution time\") OR (\"_ python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder computational coder execution time ) OR ( _ python python python programming ))*.
