Perhaps you should try some spelling variations:
"coder model complexity computational model" » "coder model complexidade computacional model" (Expand search), "coder model complexity computational modeling" (Expand search), "coder code complexity computational model" (Expand search), "coder social complexity computational model" (Expand search), "coder and complexity computational model" (Expand search), "cover model complexity computational model" (Expand search), "decoder model complexity computational model" (Expand search), "copper model complexity computational model" (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 model complexity computational model\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder model complexity computational model ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder model complexity computational model") OR ("api python python python programming"))*.
