Perhaps you should try some spelling variations:
"coder xcode java semantics and" » "coder xcode and semantics and" (Expand search), "coder xcode scalar semantics and" (Expand search), "coder xcode java semantics of" (Expand search), "code code java semantics and" (Expand search), "coder decoder java semantics and" (Expand search), "coder codes java semantics and" (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 xcode java semantics and") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder xcode java semantics and\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder xcode java semantics and ) OR ( api python python python programming ))*.
