title: Should I keep the size of stored fields in Solr to a minimum?
body: <p>I am looking to introduce Solr to power the search for a business listing website. The site has around 2 million records.</p>
  
  <p>There is a search results page which will display some key data for each result. I believe the data needed for this summary information is around 1KB per result.</p>
  
  <p>I could simply index the fields needed for the search within Solr - but this means a separate database call for each result to populate the summary information. If Solr could return all of this data I would expect it to yield greater performance than ~40 database round-trips.</p>
  
  <p>The concern is that Solr's memory usage would be too large (how might I calculate this?) and that indexing might take too long with the extra data.</p>
