Is it possible to define default mapping for an inner object in ElasticSearch? - elasticsearch

Question

Say I have a document like this:
{
"events" : [
{
"event_id" : 123,
"props" : {
"version": "33"
},
{
"event_id" : 124,
"props" : {
"version": "44a"
}
]
}
Is it possible to specify that the events.props.version be mapped to some type?
I've tried:
{
"template" : "logstash-*",
...
"mappings" : {
"_default_" : {
"properties" : {
"events.props.version" : { "type" : "string" }
}
}
}
}
But that doesn't seem to work.

Answer 1

Please have a look at mapping API in elasticsearch Mapping API.
To set any analyzer in the inner element we need to consider each and every inner field as a separate properties set. try the following
{
"mappings": {
"properties": {
"events": {
"properties": {
"event_id": {
"type": "string",
"analyzer": "keyword"
},
"props": {
"properties": {
"version": {
"type": "string"
}
}
}
}
}
}
}
}
if this not works please provide me you mapping.

Sure, but you need to use the "object" type:
From the doc ( https://www.elastic.co/guide/en/elasticsearch/reference/1.5/mapping-object-type.html ) if you want to map
{
"tweet" : {
"person" : {
"name" : {
"first_name" : "Shay",
"last_name" : "Banon"
},
"sid" : "12345"
},
"message" : "This is a tweet!"
}
}
you can write:
{
"tweet" : {
"properties" : {
"person" : {
"type" : "object",
"properties" : {
"name" : {
"type" : "object",
"properties" : {
"first_name" : {"type" : "string"},
"last_name" : {"type" : "string"}
}
},
"sid" : {"type" : "string", "index" : "not_analyzed"}
}
},
"message" : {"type" : "string"}
}
}
}
