Elasticsearch dynamic templating - elasticsearch

Question

I'm trying to get ES's (using I'm using ES v1.4.1) dynamic templating to work on my local machine and for some reason the "mappings" are not being included? I first create the index with a simple
PUT /bigtestindex (I'm using Sense plugin, not curl),
then I follow that with
PUT /_template/bigtestindex_1
{
"template": "big*",
"settings": {
"index": {
"number_of_shards": 1,
"number_of_replicas": 1
},
"analysis": {
"filter": {
"autocomplete_filter": {
"type": "edge_ngram",
"min_gram": "1",
"max_gram": "20",
"token_chars": [
"letter",
"digit"
]
}
},
"analyzer": {
"autocomplete": {
"type": "custom",
"tokenizer": "whitespace",
"filter": [
"lowercase",
"asciifolding",
"autocomplete_filter"
]
},
"whitespace_analyzer": {
"type": "custom",
"tokenizer": "whitespace",
"filter": [
"lowercase",
"asciifolding"
]
}
}
},
"mappings": {
"doc": {
"properties": {
"anchor": {
"type": "string"
},
"boost": {
"type": "string"
},
"content": {
"type": "string",
"analyzer": "whitespace_analyzer"
},
"digest": {
"type": "string"
},
"host": {
"type": "string"
},
"id": {
"type": "string"
},
"metatag.description": {
"type": "string",
"analyzer": "standard"
},
"metatag.keywords": {
"type": "string",
"analyzer": "standard"
},
"segment": {
"type": "string"
},
"title": {
"type": "string",
"index": "not_analyzed",
"fields": {
"autocomplete": {
"type": "string",
"index_analyzer": "autocomplete",
"search_analyzer": "whitespace_analyzer"
}
}
},
"tstamp": {
"type": "date",
"format": "dateOptionalTime"
},
"url": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
}
I'm not receiving any errors and the syntax looks to be correct but when I do something like
GET /bigtestindex/_mappings
in Sense, I get
{
"bigtestindex": {
"mappings": {}
}
}

Answer 1

First you need to create template then create index. You can find the same from elasticsearch documentation.
Templates are only applied at index creation time. Changing a template will have no impact on existing indices.

Answer 2

It seems my Sense command was a bit off, should have been
PUT /bigtestindex/_template/bigtesttemplate_1 (creates index and template in one command
OR
PUT /_template/bigtesttemplate_1 (creates just template) thanks to #avr for pointing out my incorrect command (needed some fresh eyes)
instead of
PUT /bigtestindex/_template/bigtesttemplate_1
discovered this after trying several things, hth someone else
UPDATE
As #avr stated, you do need to create the template first and then the index, you can create the index and the template in the same PUT statement as well.
It has everything to do with making sure your JSON is setup properly to match the right API endpoints. "mappings" should be separate from settings i.e.
{
"settings" {
...
},
"mappings" {
...
}
}
NOT
{
"settings" {
...
"mappings" {
}
}
"mappings" should NOT be included in the `"settings"` - needs to be separate.
hth, anyone else having the same problem
