索引index
查看集群状态:
GET _cat/health
查看所有index:
说明:v是用来要求在结果中返回表头
GET _cat/indices?v
GET _aliases
查看dev开头的index:
GET _cat/indices/dev*
删除指定index:
DELETE test_omp
复制或索引重命名:
### 直接复制索引到新的索引名称
POST localhost:9200/_reindex
{
"source": {
"index": "indexName"
},
"dest": {
"index": "newIndexName"
}
}
### 查询复制索引到新的索引名称
POST localhost:9200/_reindex
{
"source": {
"index": "indexName",
"type": "typeName",
"query": {
"term": {
"name": "shao"
}
}
},
"dest": {
"index": "newIndexName"
}
}

查看指定索引指定id的文档:
GET /test_gateway/_doc/L_-4DH0BA5KB_D7Szmt8
查看指定索引的所有文档(并根据指定字段排序,默认返回10条):
GET /test_gateway/_search?q=*&sort=request_log.appType.keyword:asc&pretty
或json格式:
GET /test_gateway/_search
{
"query": { "match_all": {} },
"sort": [
{"request_log.appType.keyword": "asc" }
]
}
模糊搜索:
GET prod_artwork-omp/_search?from=0&size=2
{
"query": {
"wildcard": {
"omp_request_log.uri": "upload"
}
}
}
新增文档使用PUT、POST请求。
PUT /<target>/_doc/<_id>
POST /<target>/_doc/
PUT /<target>/_create/<_id>
POST /<target>/_create/<_id>
target为索引名称,_doc为默认type。通过前两种请求可看出,id可以自行指定,也可以由ES自动生成。_create可以保证只有当文档不存在的时候进行插入,而_doc还可以用于文档更新。
插入文档(也可指定_id:POST test_omp/_doc/{_id}):
POST test_omp/_doc
{
"omp_request_log": {
"myid": "id001"
}
}
删除文档(也支持json格式):
DELETE test_omp/_doc/AQQmDn0BA5KB_D7SC_7f
POST /test_omp/_delete_by_query
{
"query": {
"match": {
"_id": "AQQmDn0BA5KB_D7SC_7f"
}
}
}
修改文档:
# 指定字段更新
POST test_omp/_update/9gUwDn0BA5KB_D7SWQLN
{
"doc": {
"omp_request_log": {
"id": "myid002"
}
}
}
# 全字段更新
POST test_omp/_doc/9gUwDn0BA5KB_D7SWQLN
{
"omp_request_log": {
"id": "myid003"
}
}
此外还可以通过脚本修改,例如将所有存在age字段的文档,其值改成5岁。
POST /user/_update_by_query
{
"script": {
"source": "ctx._source['age']=5"
},
"query": {
"bool": {
"must": [
{
"exists": {
"field": "age"
}
}
]
}
}
}
此外update和_update_by_query字段还可以修改Filed,例如将name修改成name1,这块内容使用较少,如感兴趣,请参考官方文档。
映射和类型mapping
https://blog.csdn.net/Andre_dong/article/details/109672646
include_type_name:
在Elasticsearch 6.0.0或更高版本中创建的索引只能包含一个映射类型.在5.x中创建的具有多种映射类型的索引将继续像在Elasticsearch 6.x中一样工作.映射类型将在Elasticsearch 7.0.0中完全删除。
查看指定index的映射:
GET test_omp/_mapping
添加指定index的映射(会顺带添加index):
PUT test_omp?include_type_name=false
{
"mappings": {
"properties": {
"service": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"class": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"omp_request_log": {
"properties": {
"id": {
"type": "text"
},
"requestId": {
"type": "text"
},
"requestMethod": {
"type": "keyword"
},
"uri": {
"type": "text"

"requestHeader": {
"type": "text"
},
"requestParams": {

"responseMsg": {
