Amazon search results are nigh useless for me; it absolutely refuses to constrain the results based on my terms and just fills the results with vaguely related ads that aren't even what I want.
For example, I've been trying to find what 5k2k/WUHD monitors they have, but it completely ignores that and returns WQHD/etc, so I'm no better off than just scrolling through the entire monitor category myself.
