Perhaps you should try some spelling variations:
"coder xcode and semantics of" » "coder xcode and semantic of" (Expand search), "coder xcode and semiotics of" (Expand search), "coder xcode the semantics of" (Expand search), "code code and semantics of" (Expand search), "coder decoder and semantics of" (Expand search), "coder code and semantics of" (Expand search), "coder decode and semantics of" (Expand search), "coder encode and semantics of" (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 xcode and semantics of\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder xcode and semantics of ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder xcode and semantics of") OR ("api python python python programming"))*.
