Perhaps you should try some spelling variations:
"coder code in propagation process" » "coder code in propagation problems" (Expand search), "coder code in propagation models" (Expand search), "coder code in propagation modes" (Expand search), "coder code on propagation process" (Expand search), "coder code and propagation process" (Expand search), "coder code _ propagation process" (Expand search), "code code in propagation process" (Expand search), "modern code in propagation process" (Expand search), "color code in propagation process" (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 code in propagation process\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code in propagation process ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code in propagation process") OR ("api python python python programming"))*.
