它具有这样的索引

rs-ds123584:PRIMARY> db.Task.getIndexes()
[
    {
        "v" : 2,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "ev.Task"
    },
    {
        "v" : 2,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "$**_text",
        "ns" : "ev.Task",
        "weights" : {
            "$**" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 3
    }
]

但是在进行这样的文本搜索时

rs-ds123584:PRIMARY> db.Task.find({$text:{$search: 'saf'}})
rs-ds123584:PRIMARY> db.Task.find({$text:{$search: 'x'}})

响应始终为空数组。这是什么问题看来这里的一切都是根据文档 https://docs.mongodb.com/manual/text-search/

MongoDb文本搜索返回空结果
