elasticsearch 商品搜索,英文站点

问题:

搜索关键词'testa',仅能搜索到testa的相关商品,无法搜索到test的相关商品,求解决方案:
下面是我的DSL:
{
  "query": {
    "function_score": {
      "query": {
        "multi_match": {
          "query":    "testa",
          "analyzer":"standard",
          "type": "best_fields",
          "fields": [ "name^5", "content^1" ]
        }
      },
      "field_value_factor": {
        "field":    "popular",
        "modifier": "log1p",
        "factor":   0.1
      },
      "boost_mode": "sum",
      "max_boost":  1.5
    }
  }
}

"multi_match": {
          "query":    "testa",
          "analyzer":"standard",
          "type": "best_fields",
          "fields": [ "name^5", "content^1" ],
          "fuzziness" : "AUTO",
          "prefix_length" : 2
        }

你可以试试结合should, 用fuzzy模糊匹配
