Comment:
Sorry for all the updates

   * Multi-valued fields and facets may be slow.
   * Computing statistics using stats.facet over a multi-valued field does not work properly.  https://issues.apache.org/jira/browse/SOLR-1782
   * Multi-value fields rely on UnInvertedField.java for implementation.  This is like a !FieldCache, so be aware of your memory footprint. 
-  * TrieFields of type int/float has to use a precisionStep of 32 and long/double 64 to avoid using UnInvertedField.java.
+  * TrieFields has to use a precisionStep of -1 to avoid using UnInvertedField.java. Consider using one field for doing stats, and one for doing range facetting on.
