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