Alternative for Lookahead


I was using a regex with lookahead in Trados but I am having problem in creating the same regex in Xbench. I know that lookahead is not supported in Xbench but any idea on how to deal with below issue.

Source can contain “right” and “right away” words in different scenarios.
Target should contain “sağ” word in Turkish.
I can deal with cases where the source contains “right” but not “right away” like right -“right away” with power search. But for cases where both instances of “right” word appears in source like “Please turn right and push the button right away”, I do not have a solution.

Any ideas for alternative solutions?
