--------------------------------
Summary: ToParentBlockJoinQuery fails when the parents/child fall
in to different segments
Key: SOLR-11517
URL: https://issues.apache.org/jira/browse/SOLR-11517
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.6.1
Reporter: ananthesh
We have a system where all the documents in the collections are nested child
documents. We also have 'autoCommit' enabled for the collection. We also get
huge number of document updates. We found a scenario, where 'child' documents
were indexed in one segment, while 'parent' document got indexed in the other
segment. Here are the docid looks like
0 = 95638
1 = 95639
2 = 95640
3 = 272190 {parent}
Now if the solr request has been made using "parent" query parser like the
following
{!parent which=parent:true score=max}(...)
ToParentBlockJoinQuery which handles the request wont be able to find the
parent for the searched child documents. But if we trigger `optimize` for the
same index which forces to merge all the segments to single index, the above
request will be able to fetch the results.
