推荐答案

来自: https://lucene.apache.org/core/2_9_4/queryparsersyntax.html#Escaping%20Special%20Characters

Lucene支持转义查询语法中包含的特殊字符.当前列表的特殊字符是 +-&& || ！ (){} [] ^〜*?:\

Lucene supports escaping special characters that are part of the query syntax. The current list special characters are + - && || ! ( ) { } [ ] ^ " ~ * ? : \

因此，基本上，您似乎可以对任何内容建立索引，只需对其进行转义即可.

So basically it looks like you can index anything, just have to escape it.
