Joel Bernstein commented on SOLR-10094:
---------------------------------------
I believe understand the issue. The ExportWriter makes multiple passes over the
same result set sending 30,000 results out on each pass. It appears that with
each pass over the result set we first need to reset the points for each
docValues segment. This is consistent with the bug I'm seeing which is the
first set of results are sorted properly but then things go haywire with the
sort.
> /export handler (master only) loses the sort deep into the result set

> Key: SOLR-10094
> URL: https://issues.apache.org/jira/browse/SOLR-10094
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: master (7.0)
> Reporter: Joel Bernstein
> Priority: Blocker
>
> This bug only occurs in master, and was likely introduced with the new doc
> values iterator API which is slated for 7.0.
> This bug was not caught by tests because there are no tests that have a large
> enough result set to catch the issue. As part of this ticket a test with a
> large enough result set will be added to reproduce the bug.
