My database looks like
{
"chats" : {
"-K5hUtxNOPLWwRTb8fAj" : {
"clientId" : 893,
"messages" : {
"-K5hUtyCwWuPeFT0cSXr" : {
"chatKey" : "-K5hUtxNOPLWwRTb8fAj",
"messageText" : "new message",
"timestamp" : 1450314801055,
"userId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
},
"-K5hUvwKsAOvuvt-ymFG" : {
"chatKey" : "-K5hUtxNOPLWwRTb8fAj",
"messageText" : "did this work",
"timestamp" : 1450314809127,
"userId" : "48f7a208-5647-4d0e-921c-c49595de1db2"
}
},
"newQuestion" : false,
"startedByUserId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
},
"-K5hVKjs4SkSHD7WTh1I" : {
"clientId" : 518,
"messages" : {
"-K5hVNzPKNgxLCgkfInI" : {
"chatKey" : "-K5hVKjs4SkSHD7WTh1I",
"messageText" : "this is new",
"timestamp" : 1450314928109,
"userId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
}
},
"newQuestion" : true,
"startedByUserId" : "19eaa3f0-4ab3-44b4-b418-03b64ca2313a"
}
}
}
How can I get all chats that have a newQuestion set to true? I've tried a few different queries, the latest is:
firebaseDb.child("chats/newQuestion").equalTo(true).once("value"...
But that plains about an order being needed for a boolean?

Reset to default 9You have to specify an orderBy method first.
var query = firebaseDb.child("chats").orderByChild("newQuestion").equalTo(true);
Here's the Firebase docs on querying.
