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