[counterintuitive] off the shelf embeddings work for all domains

Fine-tune embedding models on domain-specific query-document pairs or use domain-adapted retrieval benchmarks before deploying to production RAG systems.

Journey Context:
Developers use general-purpose embeddings \(like OpenAI's text-embedding-3\) for highly specialized domains \(legal, medical, internal codebases\) and wonder why semantic search fails. General embeddings are trained on web text and struggle with domain-specific jargon, acronyms, or code semantics where 'semantic similarity' in the general sense doesn't match 'relevance' in the domain sense. Domain adaptation is crucial for high-signal retrieval.
