【解决方案1】：

如果你问我这个错误很清楚，你需要在你的电影映射中为_all 指定analyzer。在Elasticsearch 2.0 中删除了设置index_analyzer。

        "_all": {
            "analyzer": "nGram_analyzer",
            "search_analyzer": "whitespace_analyzer"
        },

【讨论】：

那么什么是 index_analyzer ？你能告诉我吗
在 2.0 之前的 Elasticsearch 中，您可以设置index_analyzer、search_analyzer 或简单地设置analyzer。最后一个是将index_analyzer 和search_analyzer 设置为相同值的简写。在 Elasticsearch 2.0 中，他们将其更改为 index_analyzer 现在只是 analyzer，如果您不设置单独的 search_analyzer，则 analyzer 的值也用于此目的。
