Hi, Does anyone know what the default scorer for 4.10 is? BM25 or classic tf-idf?
I have been trying to change that, in cloud mode. I have managed to change the schema.xml in the zookeeper to add the following lines: <!-- <similarity class="solr.BM25SimilarityFactory"/> --> <similarity class="org.apache.lucene.search.similarities.LMDirichletSimilarity"/> The commented line was also tried. So I have tried different syntax, using factory without identifying additional parameters or using default, BM25 or LMDirichlet similarity. However, no matter how I did that, the final matching score never changed. I'm using standard query with lots of boosting such as title:apple^4. Please let me know what I missed to change the scorer. Thank you.
