How to respond to "what are you looking for"

Hey guys,

Just had a second date with this columbian chick and at the end she asked what I was looking for. This is the third time now I've been asked this and I still don't know how to respond. I said the same exact thing I said last time with another girl - "I would be open to something more long term but just trying to see where things go". In reality I don't want a long term relationship right now and just want to build a roster. But also I don't want to turn her off by saying that. Whats the solution to this?
