Two issues:
- literal backslashes must be escaped with a backslash.
- the comma is treated strangely, because the 'real' character in the field is a '|'. This is a bug.
The following works today.
Code:
authors:"~^\\w*\\, \\w"
I will fix the strange comma problem. After the fix is released, then the following will work
Code:
authors:"~^\\w*, \\w"
