I’ve asked this before, and found an answer to my own question; but Discourse doesn’t make it easy to search for posts so I’m asking again.
When I try to use the search bar in Safari, I can’t type ‘sc’. For example, suppose I want to look for ‘Scott’. I type the ‘s’ and a url starting with ‘s’ is suggested as usual. I type ‘c’, and it replaces what I was typing with the last thing I searched for.
How do I fix this?
Someone else was having the problem.
No answer there.
I tried restarting, to no avail. I know there’s a fix, and I probably said what it was in the other thread. Not finding what I found before.
Actually Discourse makes it very easy to search for posts. But you have to use Discourse’s search function, not your browser’s.
Type / or click on the magnifying glass icon, then enter your search terms. Click on Options for the advanced search.
Did that. When I do, the results are sub-par compared to the old board.
But that’s neither here nor there. The question is, how do I fix the inability to type words starting with ‘sc’ into the search bar.
Googling, the answer may be to clear your cookies and cache.
The search facility here is really far better than vBulletin. But if you won’t learn to use it, that’s up to you.
I can’t help you with the Safari problem, sorry.
Perhaps you missed it, but I did do, and do do, as you suggested. In your experience, it’s better than vBulletin. In my experience, vBulletin worked better.
In ‘cookies and website data’ => Manage Website Data, I removed everything. The problem persists.
What are you trying to search for that you are having difficulty finding?
I’m trying to find, in GQ, my post asking how to fix the problem, using my username, ‘created by’ and various search parameters such as “can’t type” “sc” “safari” “search bar”… whatever I can think of. I finally searched for all topics I created in GQ, sorted by date.
If you paste the below into the Discourse search box, you should get this thread directly.

I can find this thread! 
Have you tried following this advice?
Hello, I found a solution (sort of) by clearing search history. The “sc” I typed in tried to auto-fill my search bar with an expired news article that starts with “scontent-dfw5-1” that was on Facebook. Safari automatically deletes the entry for some reason.
Aha! I thought that clearing cache as I said above would delete everything. Clearing History worked. Thanks!
(FWIW, I did see the ‘scontent’ url, but it flashed by to quickly to see the rest.)
Happy to help. Now you can bookmark the post in Discourse in case you have the same problem again. 
Interesting. I tried typing “sc” and had the same problem. Clearing the history fixed it. More interesting, I could type “scout” but not “scone”.
What I’m wondering is if it will come back if you wind up visiting a URL like that again. Those are URLs for “static content” on Facebook, i.e. stuff that doesn’t change like images, scripts, etc.
There’s no reason it should be removing any URL from the address bar, so that suggests some sort of bug.
Are you using macOS Catalina, like the poster in the other thread? Or do you have the latest version, Big Sur? If the latter, then that bug is one that Apple apparently doesn’t know about.
Same problem, but even MORE interesting, I can type “scone” but not “scout”.
Whaat?! Just how interesting is this going to get?
Edit: Catalina here.
High Sierra here.
Still on Mojave.
