> Key: SOLR-11856
> URL: https://issues.apache.org/jira/browse/SOLR-11856
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 6.6.2
> Reporter: Alexander Pykhtin
> Priority: Major
>
> Attempting to do partial updates to a parent document results in losing a
> random number of children (> 50%).

> Calling /update?commit=true&softcommit=true with
> {quote}[\\\{"id":"parent:123","title":{"set":"blah"}}|file://%7B%22id%22:%22parent:123%22%2C%22title%22:%7B%22set%22:%22blah%22%7D%7D/]
> {quote}
> correctly updates title field in the parent and temporarily retains children.
> However, subsequent operation like
> /update?optimize=true
> will cause SOME of the children to drop, i.e. become orphaned. It can be one
> child, or all, or none - I was not able to figure out the system yet.
>
> EXPECTED: partial update operations should retain all the children, unless
> explicitly specified.
