Can you provide more context to your statement? Are you talking about models in general? Or specific recent models? I'm assuming "one-shot approach" is how you classify the parent comment's question (and subsequent refined versions of it).

Large models in general. A semantic query for "fake articles", without examples, is a wildcard search.

A commercial RAG solution would use Query Expansion (QE) and examples to find nearest neighbors.
