I think we all have our own ideas of who we are waiting for. The clearer we can be about that, the more likely we'll find someone who will fulfill our heart's desires. I might disagree. Having search terms might occlude some or obstruct you from noticing who is looking for you. However, there are so many soul mates out there for all of us, a few search terms probably don't matter.
Mostly, though, I don't like waiting. You have to set off down the road.
"No one treads without learning to tread - without learning how to tread by treading, without learning to remake, to retouch, the dream for whose cause the treaders have set off down the road." - Paulo Freire
