Creating multiple Page search/filtering system in best possible way

Question

I know how to create single search on products

But how do I filter products base on multiple Fields

for example search on Title, price, brand and discription at the same time

 

What would be to most professional way to achive this

 

Single filter:

public async Task<IActionResult> Index(string Title, string price, string discription , string brand)
    {
        var products = from m in _context.Product
                       select m;

        if (!string.IsNullOrEmpty(Title))
        {
            products = _context.Product.Where(x => x.Title.ToLower().Contains(Title.ToLower()));

        }
        return View(await products.ToListAsync());
    }
