Perhaps you should try some spelling variations:
"advanced functions in complexity from" » "advanced selections in complexity from" (Expand search), "advanced functionality in complexity from" (Expand search), "advanced functionalities in complexity from" (Expand search), "advanced functions on complexity from" (Expand search), "advanced functions and complexity from" (Expand search), "advanced functions _ complexity from" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: "((\"advanced functions in complexity from\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( advanced functions in complexity from ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced functions in complexity from") OR ("using in python python programming"))*.
