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 xcode java based program" » "code code java based program" (Expand search), "coder decoder java based program" (Expand search), "coder codes java based program" (Expand search), "coder xcode java baseado program" (Expand search), "coder xcode pva 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 xcode java based program\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder xcode java based program ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder xcode java based program") OR ("_ python python python programming"))*.
