title: Solr - get range facets inferior to a threshold
body: <p>I'm using Solr 4.3. I have built range facet for field price, for which I gave a <code>f.price.facet.range.start</code>, a <code>f.price.facet.range.end</code> and <code>f.price.facet.range.gap</code>, but I cant figure out how to compute the facet for values inferior or superior to a certain value.  </p>
  
  <p>Maybe I dont know the exact syntax :  <code>f.price.facet.range.other.before=1000000</code>.</p>
