## Symmetric vs. Asymmetric Semantic Search A **critical distinction** for your setup is _symmetric_ vs. _asymmetric semantic search_: - [[Symmetric Semantic Search]] - [[Asymmetric Semantic Search]] It is critical **that you choose the right model** for your type of task. Suitable models for **symmetric semantic search**: [Pre-Trained Sentence Embedding Models](https://www.sbert.net/docs/pretrained_models.html#sentence-embedding-models) Suitable models for **asymmetric semantic search**: [Pre-Trained MS MARCO Models](https://www.sbert.net/docs/pretrained-models/msmarco-v3.html), supplemented with [[Hypothetical Document Embeddings (HyDE)]] https://www.sbert.net/examples/applications/semantic-search/README.html#symmetric-vs-asymmetric-semantic-search
