Elastic Search Api 通用选项

优化返回显示

 ?pretty=true  ?format=yaml 

人类可读的

 ?human=false 

显示信息头

如 _cat 等，可以返回信息头

 v=true 

index             shard time type  stage source_host source_node target_host target_node repository snapshot files files_recovered files_percent files_total bytes bytes_recovered bytes_percent bytes_total translog_ops translog_ops_recovered translog_ops_percent

响应信息过滤

使用  filter_path  可以控制返回的信息，避免信息过多， 支持 * 只能匹配

curl -X GET "localhost:9200/_search?q=kimchy&filter_path=took,hits.hits._id,hits.hits._score&pretty"

  curl -X GET "localhost:9200/_cluster/state?filter_path=metadata.indices.*.stat*&pretty"

排除字段 -

 curl -X GET "localhost:9200/_count?filter_path=-_shards&pretty" 

错误栈信息显示

但请求有问题时，可以查看错误详情

curl -X POST "localhost:9200/my-index-000001/_search?size=surprise_me&error_trace=true&pretty"

 

Flat setting 扁平化

curl -X GET "localhost:9200/my-index-000001/_settings?flat_settings=true&pretty"
{
  "my-index-000001" : {
    "settings": {
      "index.number_of_replicas": "1",
      "index.number_of_shards": "1",
      "index.creation_date": "1474389951325",
      "index.uuid": "n6gzFZTgS664GUfx0Xrpjw",
      "index.version.created": ...,
      "index.routing.allocation.include._tier_preference" : "data_content",
      "index.provided_name" : "my-index-000001"
    }
  }
}
