推荐答案

query_string 支持Lucene语法来解释文本，其中为 multi_match 只是尝试将给定的文本 与列出的字段的索引值进行匹配。

query_string supports Lucene syntax to interpret the text, where as multi_match just attempts to match the given "text" against the listed fields' indexed values.

查询字符串因此功能更强大，但也会导致意外情况，例如 / 可能导致部分

Query string is therefore far more powerful, but it can also lead to unexpected scenarios, such as where / may cause part of the string to be interpreted as a regular expression.
