Root Cause

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

中文

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。

Workarounds

  1. 85% success 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}}`.

Dead Ends

Common approaches that don't work:

  1. 90% fail

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

  2. 80% fail

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