Perhaps you should try some spelling variations:
"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)
"coder coding using parallel programming" » "coder coding in parallel programming" (Expand search), "modern coding using parallel programming" (Expand search), "color coding using parallel programming" (Expand search), "odor coding using parallel programming" (Expand search), "coder loading using parallel programming" (Expand search), "coder modeling using parallel programming" (Expand search), "coder drying using parallel 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 coding using parallel programming\") OR (\"learning python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coding using parallel programming ) OR ( learning python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coding using parallel programming") OR ("learning python python python programming"))*.
