ElasticSearch 6.x 学习笔记：20.搜索排序，elasticsearch6.x
20.1 按照文档添加顺序排序
GET website/_search
GET website/_search
{
"query": {
"match_all": {}
}
}20.2 按照文档相关度评分排序
GET website/_search
{
"query": {
"term": {
"title": {
"value": "centos"
}
}
}
}查询结果
{
"took": 3,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {

}20.4 多字段排序
【例子】salary降序，age升序
（1）准备数据
PUT my-index
PUT my-index/persion/1
{
"name":"张三",
"age":20,
"salary":6000
}
PUT my-index/persion/2
{
"name":"李四",
"age":20,
"salary":8000
}
PUT my-index/persion/3
{
"name":"王五",
"age":21,
"salary":6000
}
PUT my-index/persion/4
{
"name":"刘六",
"age":21,
"salary":8000
}（2）salary降序，age升序
GET my-index/_search
{
"sort": [
{"salary":{"order":"desc"}},
{"age":{"order":"asc"}}
]
}{
"took": 3,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 4,
"max_score": null,
"hits": [
{
"_index": "my-index",
"_type": "persion",
"_id": "2",
"_score": null,
"_source": {
"name": "李四",
"age": 20,
"salary": 8000
},
"sort": [
8000,
20
]
},
{
"_index": "my-index",
"_type": "persion",
"_id": "4",
"_score": null,
"_source": {
"name": "刘六",
"age": 21,
"salary": 8000
},
"sort": [
8000,
21
]
},
{
"_index": "my-index",
"_type": "persion",
"_id": "1",
"_score": null,
"_source": {
"name": "张三",
"age": 20,
"salary": 6000
},
"sort": [
6000,
20
]
},
{
"_index": "my-index",
"_type": "persion",
"_id": "3",
"_score": null,
"_source": {
"name": "王五",
"age": 21,
"salary": 6000
},
"sort": [
