商品上架之后，多进行几个商品的上架，以便于后期商品检索的时候，能够进行测试

谷粒商城product的Elasticsearch索引

##查询product索引
GET product/_search

##建立product索引
PUT product
{
  "mappings": {
    "properties": {
      "skuId":{
        "type": "long"
      },
      "spuId":{
        "type": "keyword"
      },
     "skuTitle":{
       "type": "text",
       "analyzer": "ik_smart"
     },
     "skuPrice":{
       "type": "keyword"
     },
     "skuImg":{
       "type": "keyword",
       "index": false,
       "doc_values": false
     },
     "saleCount":{
       "type": "long"
     },
     "hasStock":{
       "type": "boolean"
     },
     "hotScore":{
       "type": "long"
     },
     "brandId":{
       "type": "long"
     },
     "catalogId":{
       "type": "long"
     },
     "brandName":{
       "type": "keyword",
       "index": false,
       "doc_values": false
     },
     "brandImg":{
       "type": "keyword",
       "index": false,
       "doc_values": false
     },
     "catalogName":{
       "type": "keyword",
       "index": false,
       "doc_values": false
     },
     "attrs":{
       "type": "nested",
       "properties": {
         "attrId":{
           "type":"long"
         },
         "attrName":{
           "type":"keyword",
           "index": false,
           "doc_values": false
         },
         "attrValue":{
            "type": "keyword"
         }
       }
     }
    }
  }
}

在实现检索的时候，需要品牌名字进行聚合处理，映射应该改成以下的形式

 
PUT gulimall_product
{
  "mappings": {
    "properties": {
      "attrs": {
        "type": "nested",
        "properties": {
          "attrId": {
            "type": "long"
          },
          "attrName": {
            "type": "keyword"
          },
          "attrValue": {
            "type": "keyword"
          }
        }
      },
      "brandId": {
        "type": "long"
      },
      "brandImg": {
        "type": "keyword",
        "index": false,  # 不可被检索，不生成index，只用做页面使用
        "doc_values": false # 不可被聚合，默认为true
      },
      "brandName": {
        "type": "keyword"
      },
      "catalogId": {
        "type": "long"
      },
      "catalogName": {
        "type": "keyword"
      },
      "hasStock": {
        "type": "boolean"
      },
      "hotScore": {
        "type": "long"
      },
      "saleCount": {
        "type": "long"
      },
      "skuId": {
        "type": "long"
      },
      "skuImg": {
        "type": "keyword"
      },
      "skuPrice": {
        "type": "keyword"
      },
      "skuTitle": {
        "type": "text",
        "analyzer": "ik_smart"
      },
      "spuId": {
        "type": "keyword"
      }
    }
  }
}
