Aliexpress is also surprisingly impossible to search, you gotta use external search engines, I guess it increases there sales :S More than half the time for me on AliExpress a very specific search term will just return completely unrelated things which are either trending or related to my past purchases.

I was recently looking for a cheap IOT camera in a specific form factor from aliexpress and the results were so irrelevant I had to develop alternative strategies like finding one good result and checking under its recommendations or image searching from the one good result to see other using the same picture.
