Hello everyone, I have a usecase and hope you can help me find a solution  
I have a Product index, with fields brandId and categoryId,..., I need to filter by many brandId and many categoryId and aggregate by brandId and categoryId to get the available options.  
I created a query filter to get the product

And for each filter (brandId, categoryId,...) create an aggregate query to get the available options for each filter

Is there a more effective way? Please let me know  
thank you very much
