I agree—naming is deeply underrated, and it's not at all too late! Just choose something abstract and appealing, or a simple noun without any weird associations.
What about "unheavy search" ? Synonym for light, but very uncommon as far as I can tell. It's not beautiful or elegant, but it's also not confusing and making me think of gogo dancers. Best I could come up with in 5 minutes.
Did you see that South Park episode where they try to pick a name for their startup but all names are taken? It's very, very funny.
So yeah, I want the perfect name for this. What _is_ the perfect name?
