title: How to deal with relational data in Solr
body: <p>We're right now planning to roll out Solr search for e-commerce site with faceted catalog navigation.</p>
  
  <p>We are having a little complex data schema for product and its specification attribute which are dynamic.</p>
  
  <p>We are certainly not able to understand how to map this data into the Solr? Does we need to have two indexes, one for product index and another for specification attribute that is mapped with product or just single schema. </p>
  
  <p>But how, any example will be great.</p>
