You could also try 'abc[|].*'. I find it is often easier (and less error-
prone) to use this principle than it is to escape the escaping character... :)
Just be careful with '-', it must be at the end. And it doesn't work with ']',
unless you escape it (I guess; I've never needed this).

Use 'abc\\|.*', '\' is also a special character in java that should

Hi all,
In pig, we can do pattern matching with regular expression. For a pattern
like "abc|.*", how to write the regular expression?
I tried the following:
A = FILTER B BY (name matches 'abc\|.*');
but it does not work. I cannot use 'abc|.*' because it will match
anything.
Any ideas are appreciated.
Thanks,
Zhen
