Perhaps you should try some spelling variations:
"coder and parallel complexity problem" » "coder and parallel compression problem" (Expand search), "coder and paradigms complexity problem" (Expand search), "coder and parallel complex problem" (Expand search), "coder and parallel completion problem" (Expand search), "coder and parallel convexity problem" (Expand search), "coder _ parallel complexity problem" (Expand search), "code and parallel complexity problem" (Expand search), "codes and parallel complexity problem" (Expand search), "poder and parallel complexity problem" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa 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 and parallel complexity problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder and parallel complexity problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder and parallel complexity problem") OR ("api python python python programming"))*.
