Hi, I am slowly becoming ES-addicted :-). However after reading the list archive still can't figure out the following. My document has title and tags in two languages. The title is like this: "title": { "es": "Spanish Title", "en": "English Title" } And search with query\_string finds it ok. However if I use array at the nested level: "tags": { "es": [ "tag1", "tag2", "tag3" ], "en": [ "etag1", "etag2", "etag3" ] } can´t figure out how to search for, say, "tag1". I've tried using something as tags.es and tags.eu as name files without success even when title.es does work. What I am missing? ---

Can you gist a curl recreation of the problem? thanks clint ---

Hi, thank you for the fast answer! It is strange but I can't reproduce it exactly in a new index. It seems that the problem is related to having documents with different structure inside the same type. Is this (not) allowed? For example: 1. curl -XPUT '[http://localhost:9200/nestedtest/news/1](http://localhost:9200/nestedtest/news/1)' -d '{"title": {"es": "Primer Titulo", "en": "First Title"}, "tags": {"es": ["s1","s2"], "en": ["e1", "e2"]} }' 2. curl -XPUT '[http://localhost:9200/nestedtest/news/2](http://localhost:9200/nestedtest/news/2)' -d '{"title": {"es": "Segundo Titulo", "en": "Second Title"}, "tags": {"es": ["s3","s4"], "en": ["e3", "e4"]} }' now the following PUT returns ReplicationShardOperationFailedException: 1. curl -XPUT '[http://localhost:9200/nestedtest/news/3](http://localhost:9200/nestedtest/news/3)' -d '{"title": {"es": "Tercer Titulo", "en": "Third Title"}, "tags": ["s3", "s4"] }' This doesn't work neither: 1. curl -XPUT '[http://localhost:9200/nestedtest/news/4](http://localhost:9200/nestedtest/news/4)' -d '{"title": {"es": "Cuarto Titulo", "en": "Fourth Title"}, "tags": "just text this time" }' However 3) and 4) does work in a new index, say nestedtest2 instead of nestedtest. Finally, if you start over and execute the PUTs in order 3),4),1),2) all PUTs work.

All document types have a 'mapping' or type definition, which describes how they should be indexed. You can set this mapping manually, but if you don't, then Elasticsearch will try to figure it out for you, based on the first time that it sees each field. Hence the confusion... 🙂 clint ---

I see. Thank you! So, my next step is to learn about mapping 🙂 On 20 ene, 13:11, Clinton Gormley [clin...@iannounce.co.uk](mailto:clin...@iannounce.co.uk) wrote: > On Thu, 2011-01-20 at 03:38 -0800, Svet wrote: > > > Hi, thank you for the fast answer!
