title: Can Solr/Lucene do Fuzzy Field Collapsing?
body: <p><strong>Edit</strong></p>
  
  <p>Can Solr do fuzzy field collapsing? IE collapsing fields that have similar values, rather than identical ones?</p>
  
  <p>I'd assumed that it could, but now I'm not sure, which makes my original question below invalid.</p>
  
  <p><strong>Original Question</strong></p>
  
  <p>For a large given set of values I need to decide which is the most prevalent. The set of all values will change over time, and so I can expect that the output may change over time too.</p>
  
  <p>I gather Solr can do "field collapsing" to group results by a given field, with a tolerance of similarity. Would it be possible, neigh even appropriate, to use Solr solely to collapse fields, to derive the most common value? We use Solr in other parts of the business, and it would be good to leverage existing code rather than home-brewing a custom solution.</p>
