# Catalog Semantic Encoder
A [Coveo Machine Learning (Coveo ML)](https://docs.coveo.com/en/188/) {doctitle} (CSE) [model](https://docs.coveo.com/en/1012/) leverages [vector](https://docs.coveo.com/en/nccf9008/) search and natural language processing to retrieve products that are semantically similar to the user's query.
Instead of relying solely on keyword matching, it understands the intent behind the user's query and finds relevant products based on their meaning and context.
