node.js - 没有消息的putMapping invalid_argument_exception

Question

我尝试从elasticsearch javascript客户端调用putMapping，但始终收到状态码为400，llegal_argument_exception的错误。

当我为“文档”索引调用getMapping时，得到了:

 {
"documents":{
    "mappings": {
         "properties":{
              "category":{"type":"text","fields":{"keyword": 
                         {"type":"keyword","ignore_above":256}}},
              "createdAt":{"type":"text","fields":{"keyword":                                          
                         {"type":"keyword","ignore_above":256}}},
              "id":{"type":"text","fields":{"keyword":                                                                  
                         {"type":"keyword","ignore_above":256}}},
              "info":{"type":"text","fields":{"keyword": 
                         {"type":"keyword","ignore_above":256}}},
              "text":{"type":"text","fields":{"keyword": 
                         {"type":"keyword","ignore_above":256}}},
              "title":{"type":"text","fields":{"keyword": 
                         {"type":"keyword","ignore_above":256}}},
              "visibility":{"type":"boolean"}
            }
    }
}
}

我试图用相同的属性调用putMapping并将新参数'index':'not_analyzed'添加到类别字段:

esClient.indices.putMapping({
            index: 'documents',
            type: 'document',
            body: {
                document: {
                    properties: {
                        title: { type: 'text' },
                        info: { type: 'text' },
                        text: { type: 'text' },
                        category: { type: 'text', index: 
                           'not_analyzed' 
                        },
                        visibility: { type: 'boolean' },
                        createdAt: { type: 'text' },
                    },
                },
            },
        }, (err, resp) => {
            if (err) {
                console.error(err);
            }
            else {
                console.log('Successfully Created Index', resp);
            }
        });

我收到此错误:

  }
}

Answer 1

index:'not_analyzed'-我这样做是为了使用“term”方法来精确查找字符串，但是在Elasticsearch 2.x版本中不推荐使用(index:'not_analyzed')。现在，我只使用field.keyword:'查询字符串'来查找确切的字符串。
