If not then I can create one. Currently, ScoreNodes has two issues. 1. It fails when result has only one node. 2. It triggers a GET request instead of POST. GET fails if number of nodes is large. I have been using a custom class as workaround for #2, it would be good to use the original SolrJ class. Thanks, Pratik -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
