Perhaps you should try some spelling variations:
"coder function theorem _ program" » "coder function theory _ program" (Expand search), "coder functional theory _ program" (Expand search), "coder function the _ program" (Expand search), "modern function theorem _ program" (Expand search), "power function theorem _ program" (Expand search), "over function theorem _ program" (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 function theorem _ program\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder function theorem _ program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder function theorem _ program") OR ("api python python python programming"))*.
