Mark Harwood created LUCENE-9336:
------------------------------------
Summary: RegExp.java - add support for character classes like \w
Key: LUCENE-9336
URL: https://issues.apache.org/jira/browse/LUCENE-9336
Project: Lucene - Core
Issue Type: Improvement
Components: core/other
Reporter: Mark Harwood
Assignee: Mark Harwood
Character classes commonly used in regular expressions like \s for whitespace
are not currently supported and may well be returning false negatives because
they don't throw any "unsupported" errors.
The proposal is that the RegExp class add support for the set of character
classes [defined by Java's Pattern
API|https://docs.oracle.com/javase/tutorial/essential/regex/pre_char_classes.html]
I can work on a patch if we think this is something we want to consider.
