Perhaps you should try some spelling variations:
"coder coder case complexity in" » "coder coder the complexity in" (Expand search), "coder coder and complexity in" (Expand search), "coder coder case complexity and" (Expand search), "coder decoder case complexity in" (Expand search), "code code case complexity in" (Expand search), "decoder codec case complexity in" (Expand search), "coder border case complexity in" (Expand search), "coder power case complexity in" (Expand search), "coder lower case complexity in" (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)

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder case complexity in\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder coder case complexity in ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder coder case complexity in") OR ("api python python python programming"))*.
