The current default similarity implementation of Lucene is BM25, right?
Hi
On the Lucene FAQ there is no mentioning re tf-idf or bm25 and I would
like to add some notes, but to be sure I don't write anything wrong I
would like to ask
whether the current default similarity implementation of Lucene is
really BM25, right?
as described at
https://opensourceconnections.com/blog/2015/10/16/bm25-the-next-generation-of-lucene-relevation/
Thanks
Michael

Hope it is ok like this :-)
