Is it possible to query just part of the name and get the data Like I have data 12345678 can I somehow just search for 1234?

data.whereEqualsto("data", 1234);

This is needed because the last numbers changes and the first ones doesn't.

Sure it is. When it comes to Firestore, you can simply use .startAt() as seen in the following query:

db.collection("collName").orderBy("data").startAt(1234);

When it comes to the Realtime Database, you can use .startAt() too, but as seen below:

db.child("nodeName").orderByChild("data").startAt(1234);

But remember, both queries will return elements that are greater than 1234. Since 12345678 is greater, it will be present in the result set.
