multipleQueries with fixed count of hitsPerPage for all indices

Hello everyone,

I have a website with multiple indices for each brand. All indices have the same elements for their products. category, subcategory, price, …etc.

I need to search in multiple indices and return a fixed count of hits (24) ordered by product id. The products’ ids are not repeated in any of the indices.

Is there any way to get the results that way, or should I put all products in one index??
