Perhaps you should try some spelling variations:
"coder coder coupling in program" » "coder mode coupling in program" (Expand search), "coder model coupling in program" (Expand search), "coder core coupling in program" (Expand search), "coder decoder coupling in program" (Expand search), "code code coupling in program" (Expand search), "decoder codec coupling in program" (Expand search), "coder coder coupling in programs" (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 coder coupling in program\") OR (\"_ python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder coupling in program ) OR ( _ python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder coupling in program") OR ("_ python python python programming"))*.
