实际 006-elasticsearch 查问之 1 -URI Search 查问
查问基于 movielens 数据索引。
一、URI Search 详解
1.1. URI Search 介绍
GET movies/_search?q=2012&df=title&sort=year:desc&from=0&size=10&timeout=1s
{"profile": "true"}- q: 指定查问语句。应用
Query String Syntax - df(default field): 默认字段，不指定时，会对
所有字段进行查问。 - sort: 排序
- from/size: 用于分页
- profile: 能够查看查问是如何被执行的

}二、Term vs Phrase
2.1 Term vs Phrase 区别
2.1.1 Term: Beautiful Mind ==> Beautiful OR Mind
查问含意：有
beautiful或者 有mind，两者有一个即可；
2.1.2 Phrase: “Beautiful Mind” ==> Beautiful AND Mind
查问含意：有
beautiful也要有mind, 都要有，程序也要对；
2.2 Term & Phrase 测试案例
2.2.1 Phrase 查问 - 应用引号 ””
GET movies/_search?q=title:"Beautiful Mind"Phrase 蕴含的都要有，程序也不能错，后果只匹配到一个：
