analyzer
编辑analyzer
编辑只有 text 字段支持 analyzer 映射参数。
analyzer 参数指定在索引或搜索 text 字段时用于 文本分析 的 分析器。
除非被 search_analyzer 映射参数覆盖，否则此分析器将用于 索引和搜索分析。请参阅 指定分析器。
我们建议在生产环境中使用分析器之前进行测试。请参阅 测试分析器。
analyzer 设置不能使用更新映射 API在现有字段上更新。
search_quote_analyzer
编辑search_quote_analyzer 设置允许您为短语指定分析器，这在处理禁用短语查询的停用词时特别有用。
要为短语禁用停用词，需要一个字段使用三个分析器设置
- 一个
analyzer设置，用于索引所有词项，包括停用词 - 一个
search_analyzer设置，用于删除停用词的非短语查询 - 一个
search_quote_analyzer设置，用于不删除停用词的短语查询
