elasticsearch:使用javascript创建带映射的索引

Question

我正在尝试使用官方javascript客户端创建一个带有映射的elasticsearch索引.

我的代码如下:

client.indices.create({
    index: "aName",
    "mappings": {
        "aType": {
            "properties": {
                "aProp1": { "type": "string", "index": "not_analyzed" },
                "aProp2": { "type": "string", "index": "not_analyzed" },
                "aProp3": { "type": "string", "index": "not_analyzed" },
                "aProp4": { "type": "string", "index": "not_analyzed" }
            }
        }
    }
}, function(err,resp,respcode){
    console.log(err,resp,respcode);
});

但是...索引已创建但没有映射....输出为:

undefined { ok: true, acknowledged: true } 200

我究竟做错了什么？

完善Sander Spilleman上述评论中的答案."映射"属性需要位于"body"属性中.我也在使用Javascript客户端1.3.0,文档仍然没有更新示例.

使用elastsearch在NPM 1.3.0上提供的javascript API添加一个对我有用的示例

var body = {
    tweet:{
        properties:{
            tag         : {"type" : "string", "index" : "not_analyzed"},
            type        : {"type" : "string", "index" : "not_analyzed"},
            namespace   : {"type" : "string", "index" : "not_analyzed"},
            tid         : {"type" : "string", "index" : "not_analyzed"}
        }
    }
}

client.indices.putMapping({index:"tweets", type:"tweet", body:body});

Answer 2

我尝试了相同但从索引名称得到错误.aName无效,错误是关于使用小写索引名称.然后用映射创建.

it.only('putMapping', function (done) {
    client.indices.create({
        index: "aname",
        body: {
            "mappings": {
                "aType": {
                    "properties": {
                        "aProp1": {"type": "string", "index": "not_analyzed"},
                        "aProp2": {"type": "string", "index": "not_analyzed"},
                        "aProp3": {"type": "string", "index": "not_analyzed"},
                        "aProp4": {"type": "string", "index": "not_analyzed"}
                    }
                }
            }
        }
    }, function (err, resp, respcode) {
        console.log(err, resp, respcode);
    });
})

输出:

Elasticsearch DEBUG: 2015-08-08T15:23:09Z
  starting request { method: 'POST',
    path: '/aname',
    body: { mappings: { aType: [Object] } },
    query: {} }

        "properties": {
          "aProp1": {
            "type": "string",
            "index": "not_analyzed"
          },
          "aProp2": {
            "type": "string",
            "index": "not_analyzed"
          },
          "aProp3": {
            "type": "string",
            "index": "not_analyzed"
          },
          "aProp4": {
            "type": "string",
            "index": "not_analyzed"
          }
        }
      }
    }
  }
  <- 200
  {
    "acknowledged": true
  }

Answer 3

只需在映射周围添加body:

client.indices.create({
    index: "aName",
    body: {
        "mappings": {
            "aType": {
                "properties": {
                    "aProp1": { "type": "string", "index": "not_analyzed" },
                    "aProp2": { "type": "string", "index": "not_analyzed" },
                    "aProp3": { "type": "string", "index": "not_analyzed" },
                    "aProp4": { "type": "string", "index": "not_analyzed" }
                }
            }
        }
    }
}, function (err, resp, respcode) {
    console.log(err, resp, respcode);
});

Answer 4

这些示例都不适用于ElasticSearch 5.3 API.

这是一个适用于5.3的示例.

elasticClient.indices.putMapping({
    index: indexName,
    type: "document",
    body: {
        properties: {
            title: { type: "string" },
            content: { type: "string" },
            suggest: {
                type: "completion",
                analyzer: "simple",
                search_analyzer: "simple",
                payloads: true
            }
        }
    }
})

请注意,该类型已被拉出体外,只有该类型下的子参数现在在体内.
