Question

我正在尝试在ElasticSearch中进行关键字搜索。我最初使用这个：

{
"query": {
    "filtered": {
        "filter": {
            "and": [
                {
                    "fquery": {
                        "query": {
                            "query_string": {
                                "query": "Susan Sloan",
                                "default_operator": "AND"
                            }
                        }
                    }
                }
            ]
        }
    }
}

但是，我的客户希望first_name和last_name字段中的匹配优先于其他字段中的匹配，例如家庭成员;他们不喜欢Name =“John Smith”和Spouse =“Susan Sloan”在名字=“Susan Sloan”之前出现的结果。所以我尝试将它更改为在first_name和last_name字段上具有最大提升的多匹配查询。

{
  "query": {
      "filtered": {
          "query": {
              "bool": {
                  "must": [
                      {
                          "multi_match": {
                              "fields": [
                                  "first_name^9",
                                  "last_name^9",
                                  "collection.name^7",
                                  "collection.category.name^7",
                                  "record_type.name^7",
                                  "location.city.name^7",
                                  "location.region.name^7",
                                  "location.country.name^7",
                                  "location.country.name^7",
                                  "relationships.first_name^7",
                                  "relationships.last_name^7",
                                  "attributes.name^1",
                                  "original_text^1"
                              ],
                              "query": "Susan Sloan",
                              "operator": "AND",
                              "type": "cross_fields"
                          }
                      }
                  ]
              }
          }
      }
  }
}

但是，提升似乎没有做任何事情。即使我有first_name =“Susan”和last_name =“Sloan”的记录，我得到的第一个结果是“Abel Conant”，其中“Susan”和“Sloan”出现在original_text字段中。

Answer 1

制作multi_match类型cross_fields：

"query": "Susan Sloan",
"operator": "AND",
"type": "cross_fields"

Answer 2

除了添加＆＃34;键入＆＃34;：＆＃34; cross_fields＆＃34;，我还必须添加＆＃34; analyzer＆＃34;：＆＃34;标准＆＃34;

ElasticSearch Multi Match字段提升似乎不起作用？
