索引相关操作
1、创建索引模板
# 创建模板
PUT _template/test_hot_cold_template
{
"index_patterns": "test_*",
"settings": {
"number_of_shards" : 3,
"index.number_of_replicas": 1
},
"mappings": {
"order": {
"dynamic": false,
"properties": {
"id": {"type": "long"},
"name": {"type": "keyword"}
}
}
},
"aliases": {
"test": {}
}
}
# 根据模板创建索引并写入数据
POST test_hot_cold-2019-12-01/order
{
"id":1,
"name":"cwx"
}
# 删除模板
DELETE _template/order_stpprdinf_template
2、直接创建索引
PUT my_index
{
"mappings": {
"doc": {
"properties": {
"name": {
"type": "text"
},
"blob": {
"type": "binary"
}
}
}
}
}
-- 增加字段
put my_index/_mapping/doc
{
"properties": {
"cwxtest": {"type": "keyword"}
}
}
-- 数据冷备份
PUT _snapshot/my_backup # my_backup 备份的名称
{
"type": "order",
"settings": {
"location": "/mount/backups/my_backup"
}
}
3、写入索引
PUT my_index/doc/1
{
"name": "Some binary blob",
"blob": "U29tZSBiaW5hcnkgYmxvYg=="
}
4、删除索引
DELETE my-index
5、修改索引setting
PUT /test_hot_cold-2019-12-01/_settings
{
"settings": {
"index.routing.allocation.require.hotwarm_type": "cold"
}
}
DSL query查询
--1.查询所有
GET _search
{
"query": {
"match_all": {}
}
}
--2.查询单个索引 的 固定属性
--精确匹配
GET _search
{
"query": {
"term": { "name" : "you" }
}
}
--模糊匹配
GET _search
{
"query": {
"match": { "name" : "you" }
}
}
--范围查找
GET _search
{
"query": {
"range": {
"age":{ "gte" : 15 , "lte" : 25 }
}
}
}
GET indexName/_search
{
"query": {
"wildcard":{"relateId":"*672499460503*"}
}
}
--3.功能性查询
--过滤
GET my_index/_search
{
"query": {
"bool": {
"filter": {
"term":{"age":1095}
}
}
}
}
--或 or
GET my - test / _search
{
"query": {
"bool": {
"should": [{
"term": {
"name": "you"
}
}, {
"match": {
"age": 20
}
}]
}
}
}
--与 AND
GET my-test/_search
{
"query": {
"bool": {
"must" : [{
"match" : {
"name" : "you"
}
},{
"range":{
"age":{
"from" : 10 , "to" : 20
}
}
}]
}
}
}
--必须 =
GET my_index/_search
{
"query": {
"bool": {
"must" : {
"range" : {
"age" : { "from" : 10, "to" : 20 }
}
}
}
}
}
--必须不 not
GET my_index/_search
{
"query": {
"bool": {
"must_not" : {
"term" : {
"name" : "you"
}
}
}
}
}
--复合查找
GET my_index/_search
{
"query": {
"bool": {
"should": [{
"match": {
"age": 40
}
},
{
"match": {
"age": 20
}
}],
"filter": {
"match":{
"name":"you"
}
}
}
}
}
--4.索引迁移
--场景 从A索引 复制到B索引
POST _reindex
{
"source": {
"index": "my_index"
},
"dest": {
"index": "new_my_index"
}
}
--5.基于查询的删除
POST test-index/_delete_by_query
{
"query":{
"term": {
"cameraId":"00000000002"
}
}
}
--查询
GET test-index/_search
{
"query":{
"term": {
"cameraId":"00000000002"
}
}
}
按时间范围查询:
GET order_stpprdinf_2019-12/_search
{
"size":10,
"query":{
"range":{
"order_time":{
"gte":"2019-12-11T00:00:00+08:00",
"lte":"2019-12-11T23:59:59+08:00"
}
}
}
}
按条件删除:
GET order_stpprdinf_2019-12/_delete_by_query?conflicts=proceed
{
"query":{
"range":{
"order_time":{
"gte":"2019-12-11T00:00:00+08:00",
"lte":"2019-12-11T23:59:59+08:00"
}
}
}
}
模糊匹配和范围查询
GET /_search
{
"size":0,
"query": {
"bool": {
"must": [
{"wildcard": {
"path": "/data/log/idcard.log*"
}},
{"range": {
"@timestamp": {
"gte": "2018-05-09",
"lte": "2018-05-09"
}}
}
]
}
}
}
