Hi, I have question on document relations one document can have multiple child's. and now I have to address below searches and achieve the mentioned expected results . 1. search on any child documents(meaning have a query that qualifies child documents) and retrieve the child ,parent and all of the child's of the parents 1. search on any parent documents and retrieve parent and all of the child documents 1. search on any parent documents and just retrieve only qualified parent documents 2. search on any child documents and just retrieve only qualified child documents Is there any existing feature that help in achieving this ? any ideas /thoughts would be very useful ? also please provide some sample code if possible -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I'm not sure if you can fetch both parent/child. You can certainly try by querying against the entire index (and therefore querying against your parent/child types), but we've never had any success with this. What we did to get around this was to denormalize the child documents, and let the parent be used only for matching purposes.

my understanding is nested objects (including nested filter and join) also doesnt help in this regard , correct me if am wrong On Wednesday, 14 January 2015 14:31:22 UTC-5, Ed Kim wrote: > I'm not sure if you can fetch both parent/child.

If the relationship is very simple, I don't see why not. We originally decided to denormalize part of the parent document because we wanted to minimize the payload of the returning documents. A little while later, we found out we could omit fields from the document payload, but at that point, we had a smooth running app already, so we just noted this change into our research queue.

okay .I am new to Elasticsearch and help me understand . So you mean to say with the nested objects , you can return only inner objects if required or return entire object ? If we can do this with nested objects , can you send me any sample code or example . My applications relations deals only with one parent and multiple child's and child can have it own child's and so on . Do you recommend using nested object for this kind of document relations ? Actually now thinking that I can have fake document type which holds documents in a family and don't have to bother about the how deep the relation hierarchy is Regards Nagaraju 908 517 6981 On Wed, Jan 14, 2015 at 2:54 PM, Ed Kim [edkim81@gmail.com](mailto:edkim81@gmail.com) wrote: > If the relationship is very simple, I don't see why not.

I don't know how you access elasticsearch, so the best thing I can do is offer the resource on how to manipulate the payload returned on your request: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect.

See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. Both guides will show you how to exclude/include fields from \_source, which you can use to only get the fields you want. Afterwards, check whatever client you are using to see if it supports field inclusion/exclusion. For example, there's a 'setFetchSource' method that allows you to set exclusions in the Java client api for ES.
