---------------------------------------------------------------
I added some javadocs to Document class:
- getField() / getFields() is deprecated [we may change this in LUCENE-2310]
Some thoughts:
- maybe we should make getField()/getFields() simply return null or does not
include the Field into the returned array, if its not instanceof Field? We can
add that to documentation, that lazy loaded and numerical fields are not
returned.
- I would also like to add a method Document.getNumericValue(s), that returns
Number[] or Number like the NumericField one. Like above getField() it can
return null/empty array if the field name has no numeric Fields?
The CHANGES entry may also be extended, currently it under "bugs" - we shold
move.

> Components: Index
> Reporter: Michael McCandless
> Assignee: Uwe Schindler

> (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.
