Keith Laban commented on SOLR-10047:
------------------------------------
Shalin, I wasn't sure exactly how you wanted me to submit the diff between 6.x
and master.
In this PR:
-
[Commit|https://github.com/kelaban/lucene-solr/commit/806f33e092491cc6a2ee292d2934c76171e40dc7]
adds new and old interface, and modifies all the tests to use the new interface
-
[Commit|https://github.com/kelaban/lucene-solr/commit/c38f4cabc2828ee83b53b931dd829e29a3e1701c]
reverts the tests to using the old interface.
If you want to keep both interfaces as a convenience method and tests
unmodified you can squash them all down. Otherwise use HEAD for 6.x (tests not
updated) and reset to HEAD^ for master (tests updated).
I did not write specific tests to explicitly use new/old signature because they
all use the new signature under the hood. The test I added in the original
commit tests the updated intended behavior.

> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Keith Laban
>
> The configuration of UninvertingReader in SolrIndexSearch creates a global
> mapping for the directory for fields to uninvert. If docvalues are enabled on
> a field the creation of a new segment will cause the query to fail when
> faceting/sorting on the recently docvalue enabled field. This happens because
> the UninvertingReader is configured globally across the entire directory, and
> a single segment containing DVs for a field will incorrectly indicate that
> all segments contain DVs.
> This patch addresses the incorrect behavior by determining the fields to be
> uninverted on a per-segment basis.
> With the fix, it is still recommended that a reindexing occur as data loss
> will when a DV and non-DV segment are merged, SOLR-10046 addresses this
> behavior. This fix is to be a stop gap for the time between enabling
> docvalues and the duration of a reindex.
