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