Perhaps you should try some spelling variations:
"decoder implementation _ robot programming" » "code implementation _ robot programming" (Expand search), "model implementation _ robot programming" (Expand search), "record implementation _ robot programming" (Expand search), "decoder implementation _ robots programming" (Expand search), "decoder implementation _ goal programming" (Expand search), "decoder implementation _ cone programming" (Expand search)
"python using python python programming" » "python using pythons python programming" (Expand search), "python using piton python programming" (Expand search), "python using pitons python programming" (Expand search), "python usando python python programming" (Expand search), "python coding python python programming" (Expand search), "action using python python programming" (Expand search), "python in 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: "((\"decoder implementation _ robot programming\") OR (\"python using python python programming\"))~".
• Removing quotes may allow a broader search: (( decoder implementation _ robot programming ) OR ( python using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("decoder implementation _ robot programming") OR ("python using python python programming"))*.
