根因分析

运行时字段的`script`类型被用于期望其他类型（如`keyword`或`long`）的上下文，导致类型不匹配。

English

A runtime field with a `script` type is used in a context that expects a different type (e.g., `keyword` or `long`), causing a type mismatch.

解决方案

  1. 更新运行时字段脚本以返回正确类型：`PUT my_index/_mapping {"runtime": {"my_field": {"type": "keyword", "script": {"source": "emit(doc['source_field'].value.toString())"}}}}`
  2. 在查询中使用Painless脚本转换代替运行时字段：`GET my_index/_search {"query": {"script_score": {"script": {"source": "doc['source_field'].value.length()"}}}}`

无效尝试

常见但无效的做法:

  1. Changing the runtime field type to `keyword` without adjusting the script logic 75% 失败

    The script may output incompatible values (e.g., numbers) for a keyword field, leading to further errors.

  2. Removing the runtime field and using a concrete mapping instead 60% 失败

    This requires reindexing, which is disruptive and may not be feasible in production.

  3. Setting `ignore_malformed: true` on the index to bypass type errors 90% 失败

    This only applies to concrete fields, not runtime fields, and will not resolve the context mismatch.
