本文详细介绍如何在Elasticsearch中创建模板、基于模板构建索引、添加字段、查询及维护索引，包括使用DSL进行精确查询和条件删除文档。

1.创建模板

PUT _template/template_purchaser_info
{

"order": 1,
"template": "purchaser_invoice_*",
"settings": {
"index": {
"number_of_shards": "6",
"number_of_replicas": "0",
"mapper": {
"dynamic": "false"
}
}
},
"mappings": {
"invoice": {
"properties": {
"id": {
"type": "text"
},
"invoiceType": {
"type": "keyword"
},
"invoiceNo": {
"type": "keyword"
},
"invoiceCode": {
"type": "keyword"
},
"status": {
"type": "keyword"
},
"createTime": {
"type": "date",
"format": "date_time"
},
"updateTime": {
"type": "date",
"format": "date_time"
},
"createUserId": {
"type": "keyword"
},
"createUserName": {
"type": "keyword"
}

}
}
},
"aliases": {
"purchaser_invoice_info": {}
}

}

2.基于模板建索引

匹配到映射路径即可

PUT purchaser_invoice_v1

3 给索引添加字段

POST purchaser_invoice_info/_mapping/invoice
{
   "properties": {
       "customerNo": {
           "type": "keyword"
       },
       "auditStatus": {
           "type": "keyword"
       }
   }
}

4.查看索引mapping

GET purchaser_invoice_info/_mapping

5.dsl查询

GET tax_goods/_search
{
"query": {
"match": {
"taxcodeName": "垃圾清运费"
}
}
}

6.条件删除doc

POST tax_goods/_delete_by_query
{
"query": {
"match": {
"goodsName": "垃圾清运费"
}

7.删除索引

DELETE purchaser_invoice_v1

8.获取所有模板
