["mosh (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-12441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

mosh updated SOLR-12441:
------------------------
    Environment:     (was: As discussed in [SOLR_12298|https://issues.apache.org/jira/browse/SOLR-12298], there ought to be an URP to add metadata fields to childDocuments in order to allow a transformer to rebuild the original document hierarchy.

{quote}I propose we add the following fields:
 # __nestParent__
 # _nestLevel_
 # __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".

_nestLevel_: 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.
