If I understand your use case correctly. You will have to write your own response writer. Only the below response writers are available .
Query response writer Description XMLResponseWriter The most general-purpose response format outputs its results in XML, as demonstrated by the blogging application in Part 1<http://www.ibm.com/developerworks/java/library/j-solr1/>. XSLTResponseWriter The XSLTResponseWriter applies a specified XSLT transformation to the output of the XMLResponseWriter. The tr parameter in the request specifies the name of the XSLT transformation to use. The transformation specified must exist in the Solr Home's conf/xslt directory. See Resources<http://www.ibm.com/developerworks/java/library/j-solr2/#resources> to learn more about the XSLT Response Writer. JSONResponseWriter Outputs results in JavaScript Object Notation (JSON) format. JSON is a simple, human-readable, data-interchange format that is also easy for machines to parse. RubyResponseWriter The RubyResponseWriter extends the JSON format so that the results can safely be evaluated in Ruby. If you are interested in using Ruby with Solr, follow the links to acts_as_solr<http://www.ibm.com/developerworks/java/library/j-solr2/#resources> and Flare<http://www.ibm.com/developerworks/java/library/j-solr2/#resources> in Resources<http://www.ibm.com/developerworks/java/library/j-solr2/#resources>. PythonResponseWriter Extends the JSON output format for safe use in the Python eval method. QueryResponseWriters are added to Solr in the solrconfig.xml file using the <queryResponseWriter> tag and affiliated attributes. The response type is specified in the request using the wt parameter. The default is "standard," which is set in the solrconfig.xml to be the XMLResponseWriter. Finally, instances of the QueryResponseWriter must provide thread-safe implementations of the write() and getContentType() methods used to create responses. -Ankit From: Valli Indraganti [via Lucene] [mailto:ml-node+1732965-820449511-24...@n3.nabble.com] Sent: Tuesday, October 19, 2010 11:30 AM To: Ankit Bhatnagar Subject: query results file for trec_eval Hello! I am a student and I am trying to run evaluation for TREC format document. I have the judgments. I would like to have the output of my queries for use with trec_eval software. Can someone please point me how to make Solr spit out output in this format? Or at least point me to some material that guides me through this.
