Perhaps you should try some spelling variations:
"_ python python python programming" » "_ pythons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ pitons python python programming" (Expand search)
"coder coder risk based program" » "coder decoder risk based program" (Expand search), "code code risk based program" (Expand search), "decoder codec risk based program" (Expand search), "coder code risk based program" (Expand search), "coder confer risk based program" (Expand search), "coder under risk based program" (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 coder risk based program\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder risk based program ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder risk based program") OR ("_ python python python programming"))*.
