新建索引
curl -X PUT "192.168.3.162:9200/clusterlockexception_v02" -H 'Content-Type: application/json' -d'
{
"settings": {
"blocks": {
"read_only_allow_delete": null
},
"analysis": {
"analyzer": {
"like_analyzer": {
"tokenizer": "like_tokenizer"
}
},
"tokenizer": {
"like_tokenizer": {
"type": "ngram",
"min_gram": "1",
"max_gram": "1"
}
}
}
},

"properties": {
"fileName": {
"type": "keyword"
},
"updateDate": {
"type": "date"
},
"fileFullName": {

"type": "text"
}
}
},
"url": {
"index": false,
"type": "text"
}
}
}
}
}'
新建索引時定義索引別名
在新建索引的同時，定義索引的別名，可以定義多個別名，不同別名
curl -X PUT "192.168.3.162:9200/my_index" -H 'Content-Type: application/json' -d'
{
"settings": {
// 省略...
},
"mappings": {
// 省略...
},
"aliases" : {
"alias_1" : {},
"alias_2" : {
"filter" : {
"term" : {"key" : value }
}
}
}
}'
刪除索引
curl -X DELETE "192.168.3.162:9200/company_100406_v02_v02"
上面的命令需要指定特定索引名或者通配符表達式，索引別名不能用來作爲刪除索引的參數，通配符表達式被解析爲相匹配的具體索引。
支持多索引語法，用逗號間隔。
刪除所有索引，使用 _all 或者 * 作爲索引參數。
禁止使用通配符或者 _all 來刪除索引，在配置中設置 action.destructive_requires_name 爲 true 即可。該配置可以通過使用集羣更新配置接口來修改。
添加索引別名
curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
"actions" : [
{ "add" : { "index" : "company_489521805720043520_v02", "alias" : "company_489521805720043520_alias" } }
]
}'
刪除索引別名
curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
"actions" : [
{ "remove" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_v02_alias" } }}
]
}'
修改索引別名
該操作爲原子操作
curl -X POST "192.168.3.162:9200/_aliases" -H 'Content-Type: application/json' -d'
{
"actions" : [
{ "remove" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_v02_alias" } },
{ "add" : { "index" : "company_489516259906600960_v02", "alias" : "company_489516259906600960_alias" } }
]
}'
複製索引
curl -X POST "192.168.3.162:9200/_reindex" -H 'Content-Type: application/json' -d'
{
"conflicts": "proceed",
"source": {
"index": "company_100406_alias"
},
"dest": {
"index": "company_100406_v02",
"op_type": "create",
"version_type": "external"
}
}'
刷新緩存中的索引到磁盤
curl -X POST "localhost:9200/_flush?pretty"
返回
{
"_shards" : {
"total" : 270,
"successful" : 135,
"failed" : 0
}
}
精確檢索
實際需求：除了文件名模糊匹配之外，再添加按上傳時間範圍、上傳人姓名、文件大小範圍來檢索文件信息
檢索超時設置
全局超時設置，key爲【search.default_search_timeout】，默認無設置
curl -X PUT "192.168.3.162:9200/_cluster/settings?pretty" -H 'Content-Type: application/json' -d'
{
"persistent" : {
"search.default_search_timeout" : "30s"
}
}
