根因分析

Elasticsearch中定义的搜索模板包含无效的Mustache语法，例如不匹配的花括号或错误的变量插值，导致模板解析失败。

English

A search template defined in Elasticsearch contains invalid Mustache syntax, such as mismatched braces or incorrect variable interpolation, causing template parsing to fail.

解决方案

  1. Retrieve the template definition using GET /_scripts/my_template, fix the Mustache syntax (e.g., replace unmatched '}' with '{{/query}}'), and update it using PUT /_scripts/my_template with the corrected source. Example fix: change '{{#query}} {{field}} }' to '{{#query}} {{field}} {{/query}}'.
  2. Use an inline template in the search query instead of a stored template to bypass the parsing issue temporarily: GET /_search/template { 'source': { 'query': { 'match': { 'field': '{{value}}' } } }, 'params': { 'value': 'test' } }

无效尝试

常见但无效的做法:

  1. 95% 失败

    Re-saving the template with the same invalid syntax will produce the same error; the template must be corrected first.

  2. 85% 失败

    Clearing the search template cache via POST /_cache/clear does not fix the underlying template definition.
