Perhaps you should try some spelling variations:
"coder coder variance controller hardware" » "coder coder variance control hardware" (Expand search), "coder coder impedance controller hardware" (Expand search), "coder power variance controller hardware" (Expand search), "coder model variance controller hardware" (Expand search), "coder colour variance controller hardware" (Expand search), "coder decoder variance controller hardware" (Expand search), "code code variance controller hardware" (Expand search), "decoder codec variance controller hardware" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder coder variance controller hardware") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder variance controller hardware\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( coder coder variance controller hardware ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coder variance controller hardware") OR ("_ python python python programming"))*.
