Just use Google. Reddit's built in search is useless in comparison. Yesterday I found a great thread about suit tailors in my city. The posts were all 3 years old but fortunately the tailor was still active. Digging up this info would be impossible on Discord, because at best I'd be locating individual comments asking about the topic, then scroll down to see if anybody bothered to post a response instead of changing the topic to something else.

At least it is indexed in Google. Not an excuse for Reddit's horrible search, I know, but IM doesn't even have that option.

I would disagree, searching for a topic or question on any search engine and appending 'reddit' gets me reddit discussions that are frequently relevant to my question (game tips, bugs encountered in some software, often real user reviews for products, etc).

Reddit's redesign is annoying and their own search isn't great but the alternative sources for a lot of communal information is completely inaccessible. I cannot search Google for Discord conversations and get information about my Lenovo laptop's rear thunderbolt port misbehaving, even though I witnessed that conversation take place multiple times on the unofficial Legion Discord community. If you're not on Discord and sort of active in a community it might as well not exist.

You have to use google "site:" to have any chance at all. i don't know why reddit's search is so awful

Not when you consider the type of people that unpaid moderation attracts. Reddit is broken.
