On Firebase Youtube channel there is a tutorial showing how to convert common SQL queries to Firebase.
The last query is to select all users with age = 28 and who lives in Berlin. So to get them, we need to create an index, like 28_Berlin for user, because we cannot use more than one ordering function.
But what should I do if I want to find all user with age >= 28 here?
And what to do if I need to give users ability to find each other, depending on their interests, age, location, gender? For example, if someone wants to find a male, who is interested in programming and cars, lives in New York and is from 25 to 32 years old?
Seems like I'm in a serious trouble.
