title: Date & Price field should be defined as Index or just Stored in Solr 3.6?
body: <p>Using Solr 3.6, I'm confused about considering a field as index or not..</p>
  
  <p>For specifically two field, named Created Date, and Price. I need to have filter on both of them, but can't decide whether they should be defined as Index or not in Schema.xml.</p>
  
  <p>Does it have any performance impact, and to create filter is it required to be indexed or just keeping them as stored will do the work?</p>
  
  <p>Any idea on this will be great.</p>
