----------------------------------
Summary: Mismatched Docvalue segments cause exception in
Sorting/Facting; Uninvert per segment
Key: SOLR-10047
URL: https://issues.apache.org/jira/browse/SOLR-10047
Project: Solr
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.
