| This is an example of a Space using a [`spacerini`](https://github.com/castorini/hf-spacerini) streamlit template to wrap a search engine hosted elsewhere, in this case the ChatNoir search engine. ChatNoir is an Elasticsearch-based search engine offering a freely accessible search interface for the two ClueWeb corpora and the Common Crawl, together about 3 billion web pages. This version of the search engine uses the [Search API](https://www.chatnoir.eu/doc/api/) by way of the Python [chatnoir-api](https://pypi.org/project/chatnoir-api/) Package. |
