Perhaps you should try some spelling variations:
"coder model implementation project problem" » "coder model implementation process problem" (Expand search), "cover model implementation project problem" (Expand search), "decoder model implementation project problem" (Expand search), "copper model implementation project problem" (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 implementation project problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder model implementation project problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder model implementation project problem") OR ("api python python python programming"))*.
