 Immich uses Postgres as its search database for both metadata and contextual CLIP search.
 
-Contextual CLIP search is powered by the [pgvecto.rs](https://github.com/tensorchord/pgvecto.rs) extension, utilizing machine learning models like [CLIP](https://openai.com/research/clip) to provide relevant search results. This allows for freeform searches without requiring specific keywords in the image or video metadata.
