Elasticsearch: nested object under path is not of nested type

TLDR: Put "type": "nested", in your nested type.

Say we have a normal type, and another type nested in it:

{   "some_index": {      "mappings": {         "normal_type": {            "properties": {               "nested_type": {                  "type": "nested",                  "properties": {                     "address": {                        "type": "string"                     },                     "country": {                        "type": "string"                     }                  }               },               "first_name": {                  "type": "string"               },               "last_name": {                  "type": "string"               }            }         }      }   }}

The "type": "nested", line is required for the nested queries to work which have "path": assigned to nested_type, like this:

GET /some_index/normal_type/_search{  "query": {    "nested": {      "query": {        "bool": {}      },      "path": "nested_type"    }  }}

The "type": "nested", line seems to be required in newer Elasticsearch versions only (since 1.1.1 ?).

Syntax error in query DSL. Incorrect closing for must block query->bool->must

{    "query": {        "bool": {                "must": [            }// Should be ]         }    }}

Correct version query are :

curl -XGET 'localhost:9200/thread_and_messages/thread/_search' -d '{   "query": {      "bool": {         "must": [            {               "match": {                  "thread_name": "Banana"               }            },            {               "nested": {                  "path": "messages",                  "query": {                     "bool": {                        "must": [                           {                              "match": {                                 "messages.message_text": "Banana"                              }                           }                        ]                     }                  }               }            }         ]      }   }}'
