弹性搜索-更像是返回空结果的查询

我正在使用弹性搜索来创建某种标签引擎。我正在插入文档,无法检索它。我复制问题的步骤:

PUT index
{
"mappings": {
    "taggeable" : {
        "_all" : {"enabled" : false},
        "properties" : {
            "id" : {
                "type" : "string",
                "index" : "no"
            },
            "tags" : {
                  "type" : "text"
            }
            }
        }
    }
}

2) 插入文档:

POST index/taggeable
{
"id" : "1",
"tags" : "tag1 tag2"
}

3) 使用类似以下内容的查询:

GET index/_search
{
"query": {
    "more_like_this" : {
        "fields" : ["tags"],
        "like" : ["tag1"],
        "min_term_freq" : 1
    }
}
}

但我收到:

{
"_shards": {
    "failed": 0, 
    "skipped": 0, 
    "successful": 5, 
    "total": 5
}, 
"hits": {
    "hits": [], 
    "max_score": null, 
    "total": 0
}, 
"timed_out": false, 
"took": 1
}

有人知道我做错了什么吗?我应该检索我插入的文档。
