Michael McCandless resolved LUCENE-1727.
----------------------------------------
Resolution: Fixed
> Order of stored Fields not maintained
> -------------------------------------
>
> Key: LUCENE-1727
> URL: https://issues.apache.org/jira/browse/LUCENE-1727
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 2.4, 2.4.1
> Reporter: Hoss Man
> Assignee: Michael McCandless
> Fix For: 2.9
>
> Attachments: LUCENE-1727.patch

> As noted in these threads...
> http://www.nabble.com/Order-of-fields-returned-by-Document.getFields%28%29-to21034652.html
> http://www.nabble.com/Order-of-fields-within-a-Document-in-Lucene-2.4%2B-to24210597.html
> somewhere prior to Lucene 2.4.1 a change was introduced that prevents the Stored fields of a Document from being returned in same order that they were originally added in. This can cause serious performance problems for people attempting to use LoadFirstFieldSelector or a custom FieldSelector with the LOAD_AND_BREAK, or the SIZE_AND_BREAK options (since the fields don't come back in the order they expect)
> Speculation in the email threads is that the origin of this bug is code introduced by LUCENE-1301 -- but the purpose of that issue was refactoring, so if it really is the cause of the change this would seem to be a bug, and not a side affect of a conscious implementation change.
> Someone who understands indexing internals should investigate this. At a minimum, if it's decided that this is not actual a bug, then prior to resolving this bug the wiki docs and some of the FIeldSelector javadocs should be updated to make it clear what order Fields will be returned in.
