Parent-child options

[Jean Maynier <jm...@eco2market.com>]

Hello,

Did someone find a way to solve the parent-child problem? The Join option
is too complex because you have to create multiple document type and do the
join in the query.

ElasticSearch did a better job at solving this problem:
http://www.elasticsearch.org/guide/reference/mapping/nested-type.html
http://www.elasticsearch.org/guide/reference/query-dsl/nested-query.html

Is Solr has a similar feature (at least in the roadmap) ? I don't want to
change for ES (too much changed) but it seems better for the moment for
structured content.

Lucene itself has BlockJoinQuery/Collector (in contrib/join), which is
what ElasticSearch is using under the hood for its nested documents (I
think?).

But I don't think this has been exposed in Solr yet.... patches welcome!
