This is a **work in progress** streamlit version of our [ChatNoir](https://www.chatnoir.eu/) 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] Package and is therefore not as fast as the main site. |
