> (Spinoff of LUCENE-3001)
> Today when writing stored fields we don't record that the field was a NumericField, and so at IndexReader time you get back an "ordinary" Field and your number has turned into a string.  See https://issues.apache.org/jira/browse/LUCENE-1701?focusedCommentId=12721972&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12721972
> We have spare bits already in stored fields, so, we should use one to record that the field is numeric, and then encode the numeric field in Solr's more-compact binary format.
> A nice side-effect is we fix the long standing issue that you don't get a NumericField back when loading your document.
