Product searches on Lazada feeds you products they want to sell you... not the products you ask for. Go ahead and specify a brand or style or size or whatever: they probably have it but that's not what you'll get. It won't be just what you're looking for. It might be there but it's usually not shown first. Want a specific brand? Too bad, you have to sort through all of them. Want a specific style? Too bad you have to sort through all of them. Want a specific accessory for your phone, computer, TV, guitar, or whatever? Too bad you have to sort through all of them.
Obviously, it's this way because that's the way they want it. It's entirely reasonable to show what you want first, THEN related items. Something so blatantly unhelpful can't possibly go unrecognized by them. After all these years, they obviously don't give a hoot.
I have one word for them: COMPETITORS.
