Question

我正在使用ElasticSearch河来索引CouchDB推文数据库。 “created_at”字段不符合“日期”类型，并被索引为String。如何在明确指定“created_at”为日期的情况下启动河流，以便我可以对其进行范围查询？

我尝试了以下河流请求，但它无效，该字段仍被编入索引：

curl -XPUT 'localhost:9200/_river/my_db/_meta' -d '{
    "type" : "couchdb",
    "couchdb" : {
        "host" : "localhost",
        "port" : 5984,
        "db" : "testtweets",
        "filter" : null
    },
    "index" : {
        "index" : "my_testing",
        "type" : "my_datetesting",
        "properties" : {"created_at": {
                                    "type" : "date",
                                    "format" : "yyyy-MM-dd HH:mm:ss"
                                    }
                        },
        "bulk_size" : "100",
        "bulk_timeout" : "10ms"
    }
}'

我的数据如下：
