elasticsearch通用查询参数

Elasticsearch提供了一些通用查询参数，可以用于所有REST API的查询使用

1.pretty

是否美观的显示查询结果，即对JSON数据进行格式化显示

普通请求：

GET /spring-elasticsearch-demo/_search HTTP/1.1
Host: localhost:9200
cache-control: no-cache
Postman-Token: 50167740-fc2b-492e-be16-51e760426094

{"took":2,"timed_out":false,"_shards":{"total":5,"successful":5,"skipped":0,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":[{"_index":"spring-elasticsearch-demo","_type":"person","_id":"2","_score":1.0,"_source":{"id":"2","name":"大大","description":"天天向上","age":1,"create":1535760000000}}]}}

此时，JSON数据是没有任何空格、缩进的

pretty请求：

GET /spring-elasticsearch-demo/_search?pretty HTTP/1.1
Host: localhost:9200
cache-control: no-cache
Postman-Token: 8a70e5d8-b674-4
