If you want to use Firebase UI to manage the RecyclerView, you will have to filter the results with another condition on the query.
If you can't make the query return exactly what you want, you will not be able to use Firebase UI. Instead, you will have to manually perform the query, write code to filter the results, and apply those to a RecyclerView with your own adapter.
