Hi, How can we normalize BM25 scores by the query length (number of tokens) in Lucene or elasticsearch? I can access document fields by scripting or lucene expressions in elasticsearch (https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-expression.html) but I could not find a way to get number of query tokens inside a script. So do I have to write my custom Lucene/elasticsearch query for this? Is there any other possible way?
