Have you ever used Reddit's search? If yes, did you really have a positive experience with it? Personally I found it quite terrible, UX wise in particular. Many people online seem to agree. If you're looking for something on Reddit it's actually easier to Google and restrict the site to reddit.com
I have on several occasions copy-pasted a recent post's exact title into reddit's internal search and received a mountain of irrelevant results that categorically failed to contain what I'd specified verbatim. I'm pretty sure the fucking thing is just hooked up to random number generator. It's hilariously useless.
I’ve used it on occasion…. IMO it’s not bad at finding you something related to your query, but it pales in comparison to google for finding something specific.
