Date & Price field should be defined as Index or just Stored in Solr 3.6?
===

Using Solr 3.6, I'm confused about considering a field as index or not..

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.

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?

Any idea on this will be great.
