Computed Search

Hi there,
Consider I have a schema for my products as follows:
`[{
"Name":"p1",
"Price":10000,
"Discount":0.5
},
{
"Name":"p2",
"Price":20000,
"Discount":0.3
}]`

I want to find products whose price after discount is less than 7000.
like the following predicate:
p=>p.Price*(1-p.Discount)<7000

How can I write this query in redissearch?

Thanks
