Is it possible to scale Tinder without indexes?

Tinder is a dating app with 100 Million active users. Like all dating apps, Tinder needs to run at least one query to find matches (using user set filters, etc.) for each of their users. Let's suppose that for such a query, for whatever reason, this query does not use any indexes whatsoever. Using other available resources to scale a query, would there be some way to scale such a query for an app on the scale of Tinder? If so, can you list all possible ways that you can think of?
