Perhaps you should try some spelling variations:
"coder coder and synchronization protocol" » "coder coder and synchronization protocols" (Expand search), "coder decoder and synchronization protocol" (Expand search), "code code and synchronization protocol" (Expand search), "decoder codec and synchronization protocol" (Expand search), "coder code and synchronization protocol" (Expand search), "coder codes and synchronization protocol" (Expand search), "coder poder and synchronization protocol" (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 and synchronization protocol\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder and synchronization protocol ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder and synchronization protocol") OR ("api python python python programming"))*.
