Perhaps you should try some spelling variations:
"coder coder _ sequential material" » "coder coder _ sequential aerial" (Expand search), "coder coder _ sequential lateral" (Expand search), "coder coder _ sequential factorial" (Expand search), "coder decoder _ sequential material" (Expand search), "code code _ sequential material" (Expand search), "decoder codec _ sequential material" (Expand search)
"via python python python programming" » "via pythons python python programming" (Expand search), "via piton python python programming" (Expand search), "via pitons python python programming" (Expand search), "in python 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 coder _ sequential material\") OR (\"via python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder _ sequential material ) OR ( via python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder _ sequential material") OR ("via python python python programming"))*.
