问题:

```

Caused by: NotSerializableExceptionWrapper[: Fielddata is disabled on text fields by default. Set fielddata=true on [createTime] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.]; nested: IllegalArgumentException[Fielddata is disabled on text fields by default. Set fielddata=true on [createTime] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.];

```

原因:text类型默认不支持聚合索引.

解决:

启动kibana,执行以下语句

```

PUT /索引/_mapping/类型

{

    "properties":{

        "字段":{

            "type":"text",

            "fielddata":true

        }

    }

}

```

这种问题大概率是没有手动建表，在es执行插入语句时候，es才自动建立的表。es自动建的表和你预想的不同出现的
