Perhaps you should try some spelling variations:
"coder decoder code computational program" » "coder decoder model computational program" (Expand search), "coder decoder cfd computational program" (Expand search), "coder decoder some computational program" (Expand search), "encoder decoder code computational program" (Expand search), "coder decoder codec computational program" (Expand search), "coder decoder codecs computational 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder decoder code computational program") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder decoder code computational program\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder decoder code computational program ) OR ( api python python python programming ))*.
