# Embedding
{doctitle} is a [machine learning](https://docs.coveo.com/en/188/) technique used for [natural language processing (NLP)](https://docs.coveo.com/en/ncc80129/) that converts text into numerical representations ([vectors](https://docs.coveo.com/en/nccf9008/)).
Embeddings allow vector-based search to find similarities between [items](https://docs.coveo.com/en/210/) based on meaning.
