Summary: Create UninvertDocValuesMergePolicy
Key: SOLR-10046
URL: https://issues.apache.org/jira/browse/SOLR-10046
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Keith Laban
Create a merge policy that can detect schema changes and use UninvertingReader
to uninvert fields and write docvalues into merged segments when a field has
docvalues enabled.
The current behavior is to write null values in the merged segment which can
lead to data integrity problems when sorting or faceting pending a full
reindex.
With this patch it would still be recommended to reindex when adding docvalues
for performance reasons, as it not guarenteed all segments will be merged with
docvalues turned on.
