Hi there, I need to reindex my data, and I am using the parent child relations in my index, and now i need to use the bulk api for reindexing the data. I studied the bulk api [http://www.elasticsearch.org/guide/reference/api/bulk.html](http://www.elasticsearch.org/guide/reference/api/bulk.html) but I could not understand how can I index child doc using this api, as I need to provide the parent id with the request. Please give some idea how to deal with it... Thanks Narinder Kaur -- ---

To clarify, you're not reindexing the parent documents? Is there any chance that you're setting the id as a function of the contents of the document? Or one of the fields?

If you need to index child documents via the bulk api, you can just put the parent uid in the bulk index items. The child document bulk item should look like this: { "index" : { "\_index" : "[index]", "\_type" : "[child-type]", "\_id" : "[uid]", "parent", "[parent-uid]" } } // index request for a child document { "field1" : "value1" } // the actual document soure ... // rest of bulk request. Also each line in the bulk request needs a newline. When indexing the child document, you need to know to what parent it belongs to. So you need to fetch it from somewhere (your db / storage or ES).
