Searching nested objects with parent-child relationship

Elastic Stack Elasticsearch

Hi Slobbard,

nested and parent/child are 2 different approaches to joins.

  • Nested is about storing related content in the same JSON but storing as neighbouring Lucene documents in an index.
  • Parent/child is about storing parents and children in different JSON docs but routing them to the same shard.

Each has different indexing and query apis accordingly.
