Hello isspek, Unfortunately no, it would be nice to patch RankLib to output the model in json. Jfyi, I've a script to convert the xml into the json format

I try to upload Solr Model as below example, I saw the param "model-file" given this link http://lucene.472066.n3.nabble.com/jira-Comment-Edited-SOLR-8542-Integrate-Learning-to-Rank-into-Solr-td4251260.html <http://lucene.472066.n3.nabble.com/jira-Comment-Edited-SOLR-8542-Integrate-Learning-to-Rank-into-Solr-td4251260.html> . Appearently it does not work such this configuration. Is there any support given external file with param or requiring json converter? { "class":"org.apache.solr.ltr.model.MultipleAdditiveTreesModel", "name":"ranklib-model", "features":[ {"name":"contentMatch"}, {"name":"originalScores"}, {"name":"titleMatch"} ], "params":{ "model-file":"test_data.xml" } } Bests, isspek -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
