How can I perform advanced queries in Firestore?

You can use Firestore's querying capabilities to filter, sort, and paginate your data. What specific query are you looking to perform?

I want to query documents where a field is greater than a certain value and also sort them.

You can use the where method to filter documents and the orderBy method to sort them. For example: db.collection('yourCollection').where('field', '>', value).orderBy('field');

Can I combine multiple conditions in a single query?

Yes, you can chain multiple where clauses. For instance: db.collection('yourCollection').where('field1', '>', value1).where('field2', '==', value2);

What about querying arrays or using array-contains?

You can use array-contains to check if an array field contains a specific value. For example: db.collection('yourCollection').where('arrayField', 'array-contains', value);
