  • Queries are deep by default. They always return the entire subtree.
Indexed queries with compound sorting and filtering:
  • You can chain filters and combine filtering and sort on a property in a single query.
  • Write shallow queries for sub collections; you can query subcollections within a document instead of an entire collection, or even an entire document.
  • Queries are indexed by default. Query performance is proportional to the size of your result set, not your dataset. ...
