Better results from multiple indices with one request

[Luxato]

I have an engine with 2 indices: product and category

I need to get fixed number of products and categories, in my case 32 products and 32 categories.

Although, the current Doofinder API supports search in multiple indices, it returns variable amount of prods/cats. For example it returns 30 products and 2 categories.

Right now I have to make 2 search requests: one for products, and one for categories which is redundant and slows down the whole process.
