Filter by price of child products.

[Bashev]

We have configurable products with multiple children with have different prices.
When i have a filter by super_attribute and price result comes with all products where price of any child match the prices range, but this can not be price for the selected super_attribute.

Example:
Jeans
Color: red, Price: 10$
Color: blue, Price: 20$
Color: indigo, Price: 30$

T-Shirt
Color: red, Price: 5$
Color: blue, Price: 10$
Color: yellow, Price: 20$

Current behaviour:
If i filter by color red and price 10 - 20 result will be:
T-Shirts and Jeans.
Because both of them have red colored dress in the mentioned price range.

Expected results in my case:
Jeans because only jeans have red dress in the price range 10-20$

Is it possible somehow to achieve the goals?

I'm looking at elasticsearch index and i had an idea to add also child price, but then if few products are in the selected price range and also have selected color they will be in the results, but this not means they are part of one simple product.

Probably i need every child product to be indexed as single entity, but what are the consequences there?
