根因分析

用 Mustache 语法编写的搜索模板存在格式错误的标签（未闭合的部分、不匹配的分隔符或嵌套错误），导致无法编译。

English

A search template written in Mustache syntax has malformed tags (unclosed sections, mismatched delimiters, or nested errors) that prevent compilation.

解决方案

  1. Validate the template using `POST _scripts/painless/_execute` or a Mustache linter to find unclosed sections. Fix by ensuring every `{{#section}}` has a corresponding `{{/section}}`.
  2. Simplify the template by breaking it into smaller parts and testing each with `GET /my_index/_search/template`.
  3. Use `POST _scripts/my_template` to update the template with corrected syntax, then test with `GET /_scripts/my_template`.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Loses template dynamicity, requiring separate queries for each use case, increasing code complexity.

  2. 80% 失败

    May create nested section errors if the section is already closed, leading to further parsing failures.
