ElasticSearch 给简单对象做模糊匹配

创建索引

PUT store   //创建索引

GET /store   //查看索引

DELETE store   //删除索引

创建数据结构

PUT /store/_mapping/products?pretty
{
  "properties": {
    "price": {
      "type": "long"
    },
    "name": {
      "type": "text"

    },
    "owner": {
      "type": "nested",
      "properties": {
        "name": {
          "type": "text"
        },
        "age": {
          "type": "long"
        }
      }
    }
  }
}

PUT /s*/_mapping/products
    {
      "properties": {
        "name":{
          "type": "text",
          "fields": {
            "keyword":{
                "type": "keyword",
                  "ignore_above": 256
            }
          }
        },
        "owner": {
          "type": "nested",
          "properties": {
            "name": {
              "type": "text",
              "fields": {
                "keyword": {
                  "type": "keyword",
                  "ignore_above": 256
                }
              }
            }
          }
        }
      }
    }

存储数据

POST /store/products/_bulk
{ "index": { "_id": 1 }}
{ "price" : 10, "name" : "陕西省西安市莲湖","owner":{"name" :"陕西省西安市莲湖","age":30}}
{ "index": { "_id": 2 }}
{ "price" : 20, "name" : "陕西省榆林市本地" ,"owner":{"name" :"陕西省榆林市本地","age":50}}
{ "index": { "_id": 3 }}
{ "price" : 30, "name" : "陕西省咸阳市本地","owner":{"name" :"陕西省咸阳市本地","age":20} }
{ "index": { "_id": 4 }}
{ "price" : 40, "name" : "陕西省榆林市莲湖","owner":{"name" :"陕西省榆林市莲湖","age":10} }

模糊匹配

GET /store/_search
{
  "query": {
    "match_phrase": {
      "name": ".*榆林市本地.*"
    }
  }
}

nested对象的模糊匹配

GET /store/_search
{
  "query": {
  "bool": {
    "must": [
      {
        "nested": {
          "path": "owner",
          "query": {
            "match_phrase": {
              "owner.name": ".*榆林市本地.*"
            }
          }
        }
      }
    ]
  }
  }
}
