FIREBASE WARNING: Using an unspecified index

I’m getting following error:

FIREBASE WARNING: Using an unspecified index. Consider Adding ". indexOn": "rota" at /motoristas to your security Rules for Better performance

Firebase rules:

{
    "rules": {
        ".read": "true",
        ".write": "true",
        ".indexOn": "gameSearching"
    }
}

my file.ts

initItems(serchQuery="gameSearching") {
return this.afDatabase.list('/motoristas', {
  query: {
    orderByChild: 'rota',
    equalTo: serchQuery
   }
 });
}

try to include an index in the rules nombre on the list /motoristas. Apparently this warning is occurring because the query uses a sort in a field that has no indexes.

must be something like what you’ve done here ".indexOn": "gameSearching", but to the countryside nombre.

In the official doc there is a simple example https://firebase.google.com/docs/database/security/indexing-data. In the title "Indexing with orderByChild". Something like {"rules": {"motoristas": {".indexOn": ["nombre"]}}} along with your other rules must resolve.

As we speak by the comments, add something like:

{
  "rules": {
    "motoristas": {
      ".indexOn": ["nombre"]
    }
  }
}

in its rules must resolve.
