gcbaptista opened a new issue, #11800:
URL: https://github.com/apache/lucene/issues/11800
### Description
Since release `9.1.0`, Lucene's SyntaxParser have been uncapable to parse
`@` in a query, throwing a Syntax Error (`INVALID_SYNTAX_CANNOT_PARSE`).
Version `9.0.0` is the last I tested that still can parse this character.
Two similar examples that throw `INVALID_SYNTAX_CANNOT_PARSE` in `9.1.0`,
but not in `9.0.0`:
- `\\ an@tomy`
- `\\ @natomy`
Leaving some log dump here:
`Syntax Error, cannot parse \\ an@tomy:
INVALID_SYNTAX_CANNOT_PARSE: Syntax Error, cannot parse \\ an@tomy:
