二、搜索
搜索可以分成六大类
- 1、query string search

}
]
}
}

took：耗费了几毫秒
timed_out：是否超时，这里是没有
_shards：数据拆成了5个分片，所以对于搜索请求，会打到所有的primary shard（或者是它的某个replica shard也可以）
hits.total：查询结果的数量，3个document
hits.max_score：score的含义，就是document对于一个search的相关度的匹配分数，越相关，就越匹配，分数也高
hits.hits：包含了匹配搜索的document的详细数据
2、query dsl
查询所有
|
1
2
3
4
|
get supplier/user/_search
{
"query": { "match_all": {} }
}
|
查询全部并且排序
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
get suppluer/user/_search
{
"query": {
"match_all": {}
}
, "sort": [
{
"price": {
"order": "desc"
}
}
]
}
|
分页查询
|
1
2
3
4
5
6
|
get supplier/user/_search
{
"query": { "match_all": {} },
"from": 1,
"size": 1
}
|
指定要查询显示的field
|
1
2
3
4
5
|
get supplier/user/_search
{
"query": { "match_all": {} },
"_source": ["name", "price"]
}
|
3、query filter
搜索name为‘lisi'并且price大于1500的
|

get supplier/user/_search
{
"query" : {
"bool" : {
"must" : {
"match" : {
"name" : "lisi"
}
},
"filter" : {
"range" : {
"price" : { "gt" : 1500}
}
}
}
}
}
|
4、full-text search（全文检索）
address这个字段，会先被拆解，建立倒排索引
|
1

3
4
5
6
7
8
|
get /ecommerce/product/_search
{
"query" : {
"match" : {
"address" : "bei jing"
}
}
}
|
5、phrase search（短语搜索）
跟全文检索相对应，相反，全文检索会将输入的搜索串拆解开来，去倒排索引里面去一一匹配，只要能匹配上任意一个拆解后的单词，就可以作为结果返回
phrase search，要求输入的搜索串，必须在指定的字段文本中，完全包含一模一样的，才可以算匹配，才能作为结果返回

|
get /ecommerce/product/_search
{
"query" : {
"match_phrase" : {
"address" : "bei jing"
}
}
}
|
6、highlight search（高亮搜索结果）
|

get /ecommerce/product/_search

"query" : {
"match" : {
"address" : "bei jing"
}
},
"highlight": {
"fields" : {
"address" : {}
}
}
}
