Mark Harwood commented on LUCENE-3133:
--------------------------------------
bq. I wonder if LUCENE-2454 could be extended to allow recursive
ChildDocumentQuery
No need to extend. This can be done today by nesting a NestedDocumentQuery
inside another.
The only thing you need to do is set the "ParentsFilter" to roll up results to
the appropriate point e.g. parent/child/grandchild
bq. is there a "normal" use case where you would want to put same field name on
both parent & child docs?
I wouldn't want to rule that possibility out e.g. a person has a name and age
and their sons and daughters have names and ages too.
> Fix QueryParser to handle nested fields

> Key: LUCENE-3133
> URL: https://issues.apache.org/jira/browse/LUCENE-3133
> Project: Lucene - Java
> Issue Type: Improvement
> Reporter: Michael McCandless
> Fix For: 3.2, 4.0
>
>
> Once we commit LUCENE-2454, we need to make it easy for apps to enable this
> with QueryParser.
> It seems like it's a "schema" like behavior, ie we need to be able to express
> the join structure of the related fields.
> And then whenever QP produces a query that spans fields requiring a join, the
> NestedDocumentQuery is used to wrap the child fields?
