title: Sort search results by field values in Solr
body: <p>In solr, I have a dynamic fields like first_name, revenue, address etc... Now I have to sort the results based on these dynamic field's values. I know we can only sort by int fields(eg:id). But I need to sort results by text fields also.</p>
