Since wikis on my forum aren’t overused and users don’t really know that they exist, In addition to have their title manually customized, I used Custom Top Navigation Links to add a Wiki link in the top navigation:
I also noticed that searching for "📜 [Wiki]" in:title" instead of in:wiki in:title is way faster!
By “way faster”, I mean something like three or four time faster!
You can see by yourself:
Slow: https://unicyclist.com/search?q=in%3Awiki%20in%3Atitle
Fast: https://unicyclist.com/search?q="📜%20[Wiki]"%20in%3Atitle"
So I chose the second link for my Wikis button.
I’d be interested to know why in:wiki is that slow. About 4 seconds on my computer to show the results.
Searching with the string "📜 [Wiki]" in:title" takes about 1 second.
(and of course, I understand that I can do such a wiki search based on title keywords because I only have first posts as wikis, and I customized all their title with the same prefix).
