rex field=title "(?titleNEW(.*?)(?:-))"

I have this rex command above but it still outputs the dash at the end which is in a non-capturing group- any help?

Figured this out - by changing where the new field name paranthesie was...

rex field=title "(?<titleNEW>(.*?))(?:-)"

Not sure if you have an optimal regex.  Why do you make a non capturing group of "-" and why a capture group in the named group?  This is some better:

rex field=title "(?<titleNEW>.*?):-"

 Even better, do not use * in regex when its not needed.  Do a search until you find some that its not included, like this:

rex field=title "(?<titleNEW>[^-]+)"
