title: How to highlight text in solr?
body: <p>I'm new to Solr and I'm using version 4.3.0.
  I just want to enable basic highlighting. I have created a UI using AJAX-Solr and I'm using the default request handlers. 
  Please guide me from scratch. Also, I want to enable highlighting through the request handlers and not through the query URL parameters. 
  Thanks in advance.</p>
