Perhaps you should try some spelling variations:
"coder coder complexity syntactic parallelism" » "coder coder complexity state parallelism" (Expand search), "coder coder complexity genetic parallelism" (Expand search), "coder code complexity syntactic parallelism" (Expand search), "coder model complexity syntactic parallelism" (Expand search), "coder lower complexity syntactic parallelism" (Expand search), "coder decoder complexity syntactic parallelism" (Expand search), "code code complexity syntactic parallelism" (Expand search), "decoder codec complexity syntactic parallelism" (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 complexity syntactic parallelism") OR ("_ python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder complexity syntactic parallelism\") OR (\"_ python python python programming\"))".
• Removing quotes may allow a broader search: (( coder coder complexity syntactic parallelism ) OR ( _ python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coder complexity syntactic parallelism") OR ("_ python python python programming"))*.
