== Create Index
|
||
|
|
|
||
|
|
The create index API allows to instantiate an index. ElasticSearch
|
||
|
|
provides support for multiple indices, including executing operations
|
||
|
|
across several indices. Each index created can have specific settings
|
||
|
|
associated with it.
|
||
|
|
|
||
|
|
[source,js]
|
||
|
|
--------------------------------------------------
|
||
|
|
$ curl -XPUT 'http://localhost:9200/twitter/'
|
||
|
|
|
||
|
|
$ curl -XPUT 'http://localhost:9200/twitter/' -d '
|
||
|
|
index :
|
||
|
|
number_of_shards : 3
|
||
|
|
number_of_replicas : 2
|
||
|
|
'
|
||
|
|
--------------------------------------------------
|
||
|
|
|
||
|
|
The above second curl example shows how an index called `twitter` can be
|
||
|
|
created with specific settings for it using http://www.yaml.org[YAML].
|
||
|
|
In this case, creating an index with 3 shards, each with 2 replicas. The
|
||
|
|
index settings can also be defined with http://www.json.org[JSON]:
|
||
|
|
|

|
|
[source,js]
|

|
|
--------------------------------------------------
|
||
|
|
$ curl -XPUT 'http://localhost:9200/twitter/' -d '{
|
||
|
|
"settings" : {
|
||
|
|
"index" : {
|
||
|
|
"number_of_shards" : 3,
|
||
|
|
"number_of_replicas" : 2
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}'

$ curl -XPUT 'http://localhost:9200/twitter/' -d '{

"settings" : {
|

"number_of_shards" : 3,
|
||
|
|
"number_of_replicas" : 2

}
|
||
|
|
}'

_Note you do not have to explicitly specify `index` section inside
|
||
|
|
`settings` section._

=== Mappings
|
||
|
|
|
||
|
|
The create index API allows to provide a set of one or more mappings:
|
||
|
|
|
||
|
|
[source,js]
|
||
|
|
--------------------------------------------------
|
||
|
|
curl -XPOST localhost:9200/test -d '{
|
||
|
|
"settings" : {
|
||
|
|
"number_of_shards" : 1
|
||
|
|
},
|
||
|
|
"mappings" : {
|
||
|
|
"type1" : {
|
||
|
|
"_source" : { "enabled" : false },
|
||
|
|
"properties" : {
|
||
|
|
"field1" : { "type" : "string", "index" : "not_analyzed" }
|
||
|
|
}
|
||
|
|
}
|
