More exploration gives you a higher success rate, but looking further afield makes it more likely you're actually passing one that has spawned (whether you see it or not). Ideally, you'd do both. Personally I'd just raise exploration and keep on working on my camp and you'll eventually find one in that area, most likely.
Exploring your surroundings has side benefits, though, like perhaps finding neighbors who will give you some seeds or finding unclaimed crops you can harvest.
