Missing uid for nested documents

Elastic Stack Elasticsearch
1

Hello,

I tried to use the most simple nested mapping according to the documentation
http://www.elasticsearch.org/guide/reference/mapping/nested-type/

but when I insert some data and try to scroll over them or try to open the index on localhost:9200 i get this error

FetchPhaseExecutionException[[posts_1000][1]: query[ConstantScore(NotDeleted(cache(PrefixFilter(_uid:default#))))],from[0],size[3000]: Fetch Failed [Failed to load uid from the index, missing internal _uid field, current fields in the doc [[]]]]

Has anyone come across this problem?

It was caused by turned-off type field index

http://www.elasticsearch.org/guide/reference/mapping/type-field/

We didn't need the type search so we had the index disabled. I do not know why it is actually bound with scrolling the nested documents, but after enabling the index, everything works as expected.

Can you share the search request and mapping that caused the error in your
first email?

Sure, it was the most simple properties mapping that was possible to create.

{
"default":{
"_boost":{
"name":"_boost",
"null_value":1
},
"_type":{
"store":"no",
"index":"no"
},
"_all":{
"enabled":false
},
"properties":{
"conversations":{
"type":"nested"
}
}
}
}

And I just used a web browser search like this

http://localhost:9200/testindex/default/_search?size=3000

As soon as it came across some item that had the "conversations" field not empty, it crashed with the exception I mentioned in the first e-mail.

Which version are you running? This error only seem to exists in version
0.20 and before.
