Perhaps you should try some spelling variations:
"coder decoder pattern recognition process" » "coder cover pattern recognition process" (Expand search), "coder decoder faster recognition process" (Expand search), "coder discover patterns recognition process" (Expand search), "encoder decoder pattern recognition process" (Expand search)
"_ python python python programming" » "_ pythons python python programming" (Expand search), "_ piton python python programming" (Expand search), "_ pitons 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: "((\"coder decoder pattern recognition process\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder decoder pattern recognition process ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder decoder pattern recognition process") OR ("_ python python python programming"))*.
