Perhaps you should try some spelling variations:
"coder coder complexity abc program" » "coder code complexity abc program" (Expand search), "coder model complexity abc program" (Expand search), "coder lower complexity abc program" (Expand search), "coder coder complexity and program" (Expand search), "coder coder complexity an program" (Expand search), "coder coder complexity at program" (Expand search), "coder decoder complexity abc program" (Expand search), "code code complexity abc program" (Expand search), "decoder codec complexity abc program" (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 coder complexity abc program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder complexity abc program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder complexity abc program") OR ("api python python python programming"))*.
