Perhaps you should try some spelling variations:
"coder decoder _ documentation program" » "coder decoder _ fomentation program" (Expand search), "coder decoder _ documentario programas" (Expand search), "coder decoder _ orientation program" (Expand search), "encoder decoder _ documentation 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 decoder _ documentation program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder decoder _ documentation program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder decoder _ documentation program") OR ("api python python python programming"))*.
