Hi; If you had a chance to change the code at client side I would suggest to try that: http://lucene.apache.org/solr/4_2_1/solr-solrj/org/apache/solr/client/solrj/impl/HttpSolrServer.html#setParser(org.apache.solr.client.solrj.ResponseParser) There maybe a problem about character encoding of your Play App and here is the information:
Javabin is a custom binary format used to write out Solr's response in a fast and efficient manner. As of Solr 3.1, the JavaBin format has changed to version 2. Version 2 serializes strings differently: instead of writing the number of UTF-16 characters followed by the bytes in Modified UTF-8 it writes the number of UTF-8 bytes followed by the bytes in UTF-8. Which version of Solr and Solrj do you use respectively? On the other hand if you give us more information I can help you because there may be any other interesting thing as like here: https://issues.apache.org/jira/browse/SOLR-5744 Thanks; Furkan KAMACI 2014-04-12 22:18 GMT+03:00 Prashant Golash <prashant.gol...@gmail.com>: > Hi Solr Gurus, > > I have some doubt related to solrj client. > > My scenario is like this: > > - There is a proxy server (Play App) which internally queries solr. > - The proxy server is called from client side, which uses Solrj library. > The issue is that I can't change client code.
