Elasticsearch change from 0.90 (0.90.x) to 1.2 (1.x) API-Two

This article is for the translation of official documents and personal understanding. When the author translates, the version of Elasticsearch (hereinafter referred to as ES) is 1.2.2. Please support original: http://www.cnblogs.com/donlianli/p/3836768.html I. Changes in statistical information-related ordersFor cluster state Cluster_state, node information Nodes_info, node statistics nodes_stats and index Information indices_stats command format are unified, such as viewing the cluster information using command:

Curl-xget Http://localhost:9200/_cluster/state/nodes?pretty=1

To view node statistics:

Curl-xget http://localhost:9200/_nodes/stats?pretty=1 Cluster statistical information Curl-xget Http://localhost:9200/_cluster/stats?pretty=1

Second, index-related API

The order of mapping, alias, settings, and warmer related commands and parameters is adjusted. The new order and format are as follows:

Curl-xput http://Localhost:9200/{indices}/_mapping/{type}Curl-xput http://Localhost:9200/{indices}/_alias/{name}Curl-xput http://Localhost:9200/{indices}/_warmer/{name}Curl-xget http://Localhost:9200/{indices}/_mapping/{types}Curl-xget http://Localhost:9200/{indices}/_alias/{names}Curl-xget http://Localhost:9200/{indices}/_settings/{names}Curl-xget http://Localhost:9200/{indices}/_warmer/{names}Curl-xdelete http://Localhost:9200/{indices}/_mapping/{types}Curl-xdelete http://Localhost:9200/{indices}/_alias/{names}Curl-xdelete http://Localhost:9200/{indices}/_warmer/{names}

where {Indices},{type} and {name} can be any of the following:

• _all, * or empty, these 3 values mean the same, representing all possible values
• Wildcard characters, such as "test*"
• Comma-delimited list, for example: index_1,test_*

The only exception is the delete command, which does not receive an empty value. If you want to delete anything, you must specify it explicitly. Similarly, the results returned by the GET command are also unified.

1. A specific value is returned only if the query has a result, otherwise, only an empty object {} is returned. When the mapping,warmer,alias,setting of a query does not exist, 404 is no longer returned.
2. If the result is queried, the result always contains the index name, then the section, and then the element name. For example:

{
"My_index": {
"Mappings": {
"My_type": {...}
}
}
}

Above is the result returned by the Get_mapping API.

In the future we'll also provide plural versions to allow putting multiple mappings etc in a single request.

It's like saying that you can set up two versions of mappings in a request.
