    Resolution: Duplicate

> Add deeply nested documents URP

>                 Key: SOLR-12440
>                 URL: https://issues.apache.org/jira/browse/SOLR-12440
>             Project: Solr
>          Issue Type: New Feature
>      Security Level: Public(Default Security Level. Issues are Public) 
>         Environment: As stated in SOLR-12298, there ought to be an URP to add metadata fields to solr child documents, so the full original document hierarchy can be rebuilt using a transformer.
> {quote}1. __nestParent__
>  2. __nestLevel__
>  3. __nestPath__
> __nestParent__: This field wild will store the document's parent docId, to be used for building the whole hierarchy, using a new document transformer, as suggested by Jan on the mailing list.
> __nestLevel__: This field will store the level of the specified field in the document, using an int value. This field can be used for the parentFilter, eliminating the need to provide a parentFilter, which will be set by default as "_level_:queriedFieldLevel".
> __nestPath__: This field will contain the full path, separated by a specific reserved char e.g., '.'
>  for example: "first.second.third".
>  This will enable users to search for a specific path, or provide a regular expression to search for fields sharing the same name in different levels of the document, filtering using the level key if needed.
