Question

我正在尝试找一个匹配区分大小写的名称。当我尝试下面的代码时，它按预期工作，不区分大小写。

        HashMap<String, String> data = new HashMap<String, String>();
        data.put("GroupId", "3");
        data.put("GroupName", "testGroup three");
        data.put("CreatedDateTime", "20180115130026757+0000");
        data.put("UpdatedDateTime", "20180115130026757+0000");
        data.put("Createdby", "3");
        data.put("GroupUser",  "{1,2,3,4}");
        data.put("status", "active");

        String mapping = {"typename":{"properties":{
        "GroupName":{"type":"text","index":"not_analyzed"},
        "Createdby":{"type":"text","index":"not_analyzed"},
        "GroupUser":{"type":"text","index":"not_analyzed"},
        "UpdatedDateTime":{"type":"text","index":"not_analyzed"},
        "CreatedDateTime":{"type":"text","index":"not_analyzed"},
        "GroupId":{"type":"text","index":"not_analyzed"},
        "status":{"type":"text","index":"not_analyzed"}}}}

        client = new PreBuiltTransportClient(settings).addTransportAddresses(new TransportAddress(new InetSocketAddress(ipaddress, port)));

        //inserting record
        IndexResponse response = client.prepareIndex(indexName, typeName).setSource(data).get();

        //inserting mapping
        client.admin().indices().preparePutMapping(indexName)
        .setType("typeName")
        .setSource(mapping, XContentType.JSON)
        .get();

为了找到区分大小写的值，我发现要将索引用作not_analyzed。我尝试了以下

        HashMap<String, String> data = new HashMap<String, String>();
        data.put("GroupId", "3");
        data.put("GroupName", "testGroup three");
        data.put("CreatedDateTime", "20180115130026757+0000");
        data.put("UpdatedDateTime", "20180115130026757+0000");
        data.put("Createdby", "3");
        data.put("GroupUser",  "{1,2,3,4}");
        data.put("status", "active");

        String mapping = {"typename":{"properties":{
        "GroupName":{"type":"text","index":"not_analyzed"},
        "Createdby":{"type":"text","index":"not_analyzed"},
        "GroupUser":{"type":"text","index":"not_analyzed"},
        "UpdatedDateTime":{"type":"text","index":"not_analyzed"},
        "CreatedDateTime":{"type":"text","index":"not_analyzed"},
        "GroupId":{"type":"text","index":"not_analyzed"},
        "status":{"type":"text","index":"not_analyzed"}}}}

        client = new PreBuiltTransportClient(settings).addTransportAddresses(new TransportAddress(new InetSocketAddress(ipaddress, port)));

        //inserting record
        IndexResponse response = client.prepareIndex(indexName, typeName).setSource(data).get();

        //inserting mapping
        client.admin().indices().preparePutMapping(indexName)
        .setType("typeName")
        .setSource(mapping, XContentType.JSON)
        .get();

我得到一个例外，如下所示

 java.lang.IllegalArgumentException: Could not convert [GroupName.index] to boolean

我想完成以下两种情况：

 1. Find by case sensitive
 2. Find by case insensitive.

弹性搜索版本为6.1.2。

非常感谢任何帮助。

UPDATE-1

根据@Val，我已将代码更改为：

    HashMap<String, String> data = new HashMap<String, String>();
    data.put("GroupId", "3");
    data.put("GroupName", "testGroup three");
    data.put("CreatedDateTime", "20180115130026757+0000");
    data.put("UpdatedDateTime", "20180115130026757+0000");
    data.put("Createdby", "3");
    data.put("GroupUser",  "{1,2,3,4}");
    data.put("status", "active");

    String mapping = {"typename":{"properties":{
    "GroupName":{"type":"keyword"},
    "Createdby":{"type":"keyword"},
    "GroupUser":{"type":"keyword"},
    "UpdatedDateTime":{"keyword":"text"},
    "CreatedDateTime":{"keyword":"text"},
    "GroupId":{"type":"keyword"},
    "status":{"type":"keyword"}}}}

    client = new PreBuiltTransportClient(settings).addTransportAddresses(new TransportAddress(new InetSocketAddress(ipaddress, port)));

   client.admin().indices().prepareCreate("indexName").get(); 

    //inserting mapping
    client.admin().indices().preparePutMapping(indexName)
    .setType("typeName")
    .setSource(mapping, XContentType.JSON)
    .get();

    //inserting record
    IndexResponse response = client.prepareIndex(indexName, typeName).setSource(data).get();

现在我可以插入了。但是当我在GroupName中搜索一个值时，结果为空。

不推荐使用

not_analyzed，而是需要使用keyword。

请尝试下面的映射：

String mapping = {
  "typename": {
    "properties": {
      "GroupName": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          }
        }
      },
      "Createdby": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          }
        }
      },
      "GroupUser": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          }
        }
      },
      "UpdatedDateTime": {
        "type": "date",
        "format": "yyyyMMddHHmmssSSSZ"
      },
      "CreatedDateTime": {
        "type": "date",
        "format": "yyyyMMddHHmmssSSSZ"
      },
      "GroupId": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          }
        }
      },
      "status": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          }
        }
      }
    }
  }
}

还要确保在插入数据之前插入映射，即

执行：

//inserting mapping

之前：

//inserting record

无法插入＆＃34;索引＆＃34;：＆＃34; not_analyzed＆＃34;在弹性搜索的映射中6.1.2
