_type field
editEach document indexed is associated with a _type (see
Mapping Types) and an _id. The _type field is
indexed in order to make searching by type name fast.
The value of the _type field is accessible in queries, aggregations,
scripts, and when sorting:
# Example documents
PUT my_index/type_1/1
{
"text": "Document with type 1"
}
PUT my_index/type_2/2?refresh=true
{
"text": "Document with type 2"
}
GET my_index/_search
{
"query": {
"terms": {
"_type": [ "type_1", "type_2" ]
}
},
"aggs": {
"types": {
"terms": {
"field": "_type",
"size": 10
}
}
},
"sort": [

}
}
],
