Question about Hingis' DOUBLES career

I can't believe I've searched google for a long-ass time with NOTHING to show for it. Hingis defeated the Williams sisters twice in doubles. Once with Seles, and once with....? Who was her partner, and where was the match, what was the score? There is NOTHING on the internet about this match, you would think that such high profile players with near perfect doubles careers would have their doubles h2h plastered everywhere?!
