Overview
Today the default scoring algorithm in Elasticsearch is TF/IDF. This default will change to BM25 once Elasticsearch switches to Lucene 6. In this talk, Britta will tell you all about BM25 – what it is, how it differs from TF/IDF and other scoring techniques, and why it might be the better default going forward.
