Perhaps you should try some spelling variations:
"coder simulation model using programmer" » "code simulation model using programmer" (Expand search), "model simulation model using programmer" (Expand search), "power simulation model using programmer" (Expand search), "coder simulation model housing programmes" (Expand search), "coder simulation model housing programme" (Expand search), "coder simulation model easing programmes" (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 simulation model using programmer\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder simulation model using programmer ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder simulation model using programmer") OR ("api python python python programming"))*.
