Varun Thacker commented on SOLR-11550:
--------------------------------------
Hi Ananthesh,
Parent and child documents used to have different {{_version_}} values . This
was addressed in SOLR-10114.
Although the reason behind fixing that was re-ordered DBQ queries.
What's the difference between this Jira and SOLR-11517 that you had filed?
Also is this reproducible ?

> We are using the _addChildDocument_ functionality of the solrj, along with
> the _overwrite_ parameter set _true_. We do have configured the softCommit
> and hardCommit. What we are observing is that the parent document and the
> child document have different '\_version\_', along with the parent and child
> documents are not consecutive. Here it looks like
> {noformat}
> {
> "id":"8197105",
> "_version_":1582256304742727680,
> "[docid]":274136},
> {
> "id":"10073563",
> "_version_":1582255855082930176,
> "[docid]":140176},
> {

> "id":"10073563_8355551",
> "_version_":1582255855082930176,
> "[docid]":140174},
> {
> "parentId":"8197105",
> "id":"8197105_8197109",
> "_version_":1582255855066152960,
> "[docid]":140173},
> {
> "parentId":"8197105",
> "id":"8197105_8197108",
> "_version_":1582255855066152960,

> {noformat}
> In the above example mentioned, _parentId_ represents the _parentId_ of the
> document. While, those documents does not have the _parentId_ represents
> parent document. As per the above example, between the parent-child
> documents of 8197105, there is another set of parent-child document which got
> indexed which belong to 10073563.
> Because of the above issue, BlockJoinQuery will start returning wrong results
