Hi, I am working on the migration of SOLR 5.4 to 7.1 and I have not been able to get the same order in the results. Looks like the problem is with the bf parameter.
We use edismax with both boost and bf functions. It is important to have some functions as bf so they add to the score and the impact is less than the ones in the boost parameter. I have tried overriding the similarity class by specifying the following in schema.xml but I am still not able to get the same score and order of results with equal queries in 5.4 and 7.1 <similarity class="org.apache.lucene.search.similarities.ClassicSimilarity" /> We are also using qf to boost some query fields. Enabling debug=true I noticed that 5.4 uses the queryNorm as the boost value of the bf formulas. Version 7.1 is using a boost value of 1 in all bf formulas. Is there a way to configure 7.1 so it uses queryNorm in bf and produces the same results as 5.4? Thanks, Homero.
