怎么办ealsticsearch中的不敏感搜索（5.3.2）？

Question

问题此聚合提供所有“窗口”，但它区分大小写。如何进行不区分大小写的搜索？

GET /record_new/_search
{"size":0,
  "aggs" : {
        "software_tags" : {
            "terms" : {
                "field" : "software_tags.keyword",
                  "include" : ".*Windows.*",
                  "size" : 10000,
                  "order" : { "_term" : "asc" }

                        }
                 }
          }

}

映射

  "record_new": {
    "mappings": {
      "record_new": {
        "software_tags": {
          "full_name": "software_tags",
          "mapping": {
            "software_tags": {
              "type": "text",

                  "ignore_above": 256
                }
              },
              "fielddata": true
            }
          }
        }
      }
    }
  }
}

我认为你完全错了。搜索和获取唯一值是不同的事情。以下方法怎么样？

请注意，我对聚合使用了稍微不同的设置，我添加了query。

GET record_new/_search
{
  "size": 0,
  "query": {
    "term": {
      "software_tags": {
        "value": "windows"
      }
    }
  },
  "aggs": {
    "software_tags": {
      "terms": {
        "field": "software_tags.keyword",
        "include" : ".*Windows.*",
        "size": 10000,
        "order": {
          "_count": "desc"
        }
      }
    }
  }
}
