the order of fields in Document.fields()

[ro...@xemaps.com]

Quick question about Document.fields().

Lucene provides you with a method to retrieve the value of a field or grab
all fields as an Enumeration.  It does not, however, allow you to grab all
values of one field for a document, it will only return the last value added
for that field.  

For example, I am indexing email messages that might have multiple To/CC/BCC
fields in the message header.  Currently to grab all the values when I
display an email that has been indexed, I must use the fields() method to
grab an Enumeration of all fields in a document.  I then separate them into
different arrays based on the field names.  However I am concerned about the
order of the fields since I consider the first To or CC or BCC to be the
main value for each field.  

Is the order of the fields returned in the order that they are added?  Or is
there no order?  If there is no order, can someone suggest a solution?

Thanks!

Roy.

The order is preserved (or reversed actually), so it's not random.
It's reverse of the order of the order in which the fields were added
to the document.

This would be easy to test...
