 <p>In solr, if you use dismax or edismax query parser, you can use payloads. We did this whit good results in solr 3.6. As a starting point I recomand: <a href="http://searchhub.org/dev/2009/08/05/getting-started-with-payloads/" rel="nofollow">solr payload</a> and: <a href="http://digitalpebble.blogspot.ro/2010/08/using-payloads-with-dismaxqparser-in.html" rel="nofollow">solr paylaod 2</a> Hope that will help.</p>
