Perhaps you should try some spelling variations:
"coder user modeling complexity and" » "coder user model complexity and" (Expand search), "coder user modeling complex and" (Expand search), "coder user governing complexity and" (Expand search), "poder usar modeling complexity and" (Expand search), "code use modeling complexity and" (Expand search), "codes used modeling complexity 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder user modeling complexity and\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder user modeling complexity and ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder user modeling complexity and") OR ("api python python python programming"))*.
