使用elasticssearch客户端创建索引 [英] using elasticssearch client to create indices

问题描述

我正在尝试在nodejs中使用elasticsearch的官方客户端来为chouchDB创建索引。真的很感激任何帮助。

I am trying to use elasticsearch's official client in nodejs to create indices for chouchDB. Will really appreciate any help.

这就是我创建索引的方式：

This is how I am creating an index:

esClient.indices.create({index: "users_index",
            body: {
                "type" : "couchdb",
                "couchdb" : {
                    "host" : "localhost",
                    "port" :"5984",
                    "db" :"users"
                },
                "index" : {
                    "index" : "users_index",
                    "type" : "users",
                    "bulk_size" : "100",
                    "bulk_timeout" : "10ms"
                }
            }}).then(function(x){
                console.log(x);
                callback(null);
            },
            function(err){
                console.log(err);
                callback(null);
            });

当我在意义上搜索这样的数据时（GET users_index / users_index / _search），我得到了这个没有任何数据：
{
take：1，
timed_out：false，
_shards：{
total：1，
成功：1，
失败：0
}，
点击：{
总计：0，
max_score： null，
点击：[]
}
}

When I search for data like this in sense (GET users_index/users_index/_search), I get this without any data: { "took": 1, "timed_out": false, "_shards": { "total": 1, "successful": 1, "failed": 0 }, "hits": { "total": 0, "max_score": null, "hits": [] } }

我真的很感激任何帮助。

I'll really appreciate any help.

在创建索引之前，我还尝试创建索引模板，以便我的所有索引都获得相同的映射。我这样做就像以下一样。我没有走那么远来验证它是否正确。如果有任何错误，请告诉我。

Before creating index, I am also trying to create an index template so that all my indices get the same mapping. I am doing it like following. I have not gone that far to verify if its correct. Please let me know if there are any errors in this.

esClient.indices.putTemplate({
            name: "vw_index_template",
            body:{
                "template" : "*_index",
                "settings" : {
                    "number_of_shards" : 1
                },
                "mappings" : {
                    "id_prkey_template" : {
                        "properties" : {
                            "_id" : {"type" : "string", "index": "not_analyzed"},
                            "prkey" : {"type" : "string", "index": "analyzed"}
                        }
                    }
                }
            }
        }).then(function(res){
            console.log(res);
            callback(null);

        }, function(error){
            console.log(error);
            callback(null);
        });

非常感谢任何帮助。

非常感谢。

推荐答案

您无法将文档（正文）附加到 indices.create （见这里）。如果您只想将新文档索引到现有或不存在的索引中，则应使用 index ，例如：

You can't attach a document (body) to indices.create (see here). If you want to simply index new documents into a either existing or non-existing index you should use index, for example:

esClient.index({
  index: "users_index",
  type: "couchdb",
  body: {
    field1: 'test',
    field2: 123
  }
}).then(function (x) {
    console.log(x);
    callback(null);
  },
  function (err) {
    console.log(err);
    callback(null);
  });

此外，您不应为 _id 字段，因为它是一个内部ES字段。

Also, you shouldn't specify any mapping for the _id field since it's an internal ES field.
