【问题背景】：客户在visualize查询数据报错有一个分片失败，报错如下图
【排查思路】
通过让客户提供kibana请求的har包解析分析到的dsl如下

}在es查询后报错如下

}
}
}
]
},
"hits": {
"total": 0,
"max_score": 0,
"hits": []
}}检查了客户的mapping 有两个timestamp字段，通过timestamp range查询报错number_format_exception、通过@timestamp range查询报错illegal_argument_exception。kibana默认是用@timestamp筛选数据的，那我们尝试把上面dsl range查询更换为@timestamp会怎么样。报错如下

"reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default.

}
}
]
},
"hits": {
"total": 0,
"max_score": 0,
"hits": []
}
}【原因分析】
Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [code_version] in order to load field data by uninverting the inverted index. Note that this can use significant memory这个错误意味着正在尝试在code_version字段上执行需要每个文档的字段数据的操作，如聚合和排序。问题原因是客户的mapping与之前的索引mapping不一致，多个字段type变成了text+keyword。默认情况下，文本字段不适用于这些操作。解决此问题的方法是将该字段更改为关键字字段，或者将`fielddata=true`设置为该字段，以便通过反转倒排索引来加载字段数据。但需要注意，这可能会使用大量内存。
【解决方案】把code_version字段启用一下`fielddata=true`后查询正常
找到需要启用fielddata的字段，并更新其映射。例如，如果要将名称为"my_field"的字段的fielddata设置为true，可以使用以下请求：
PUT /my_index/_mapping
{
"properties": {
"my_field": {
"type": "text",
"fielddata": true
}
}
