Searching for someone on facebook by their career?

Hi, I am trying to find a co-worker on facebook. We both talked about adding each other on facebook and I can't seem to find them. I only know their first name and that they work where I work. I've tried searching for their name and narrowing it down to the place I work and the town along with their name but couldn't find her. Is there a way to search for someone by career alone? Like instead of typing in a name you can just search for a work location and a town... I think she might go by a nickname at work.
