[counterintuitive] Is high cosine similarity in embeddings sufficient for semantic relevance

Combine embedding similarity with metadata filtering, keyword search \(hybrid search\), or re-ranking models to ensure task-specific relevance.

Journey Context:
RAG pipelines often rely solely on vector similarity to retrieve context. Embeddings compress meaning into a single vector, losing nuance. High similarity might just mean the documents share topic or syntax, not that they answer the specific question. Opposite meanings can have similar embeddings \(e.g., 'I love this' vs 'I do not love this'\).
