Re: REGEX: Search two fields in WV's "text_query"?
not sure if I got this right but anyway. I assume that the text is stored in a single attribute. Then just perform an AttributeCopy and use the Replace operator twice with different capturing groups. Or you replace it within a replace operation and two capturing groups $1 and $2 followed by the new split operator.
