Brave is now disabling the ability to add other search engines, really slimy behavior by the developers, shame on them.
My setup:
Version 1.43.93 Chromium: 105.0.5195.127 (Official Build) (64-bit)
Ubuntu 22.04
Two methods to add it suggested by others on the forums (not intuitive, once again brave is being underhanded and using dark patterns to prevent this). Presearch will not show up on either method.
Method#1
If Presearch support open-search, then you can add it yourself (it’ll listed under “Recent visited” under Settings > Search Engine).
Method#2
1 - Go to this link https://engine.presearch.org/
(Login if it’s shows you not logged in because i was already logged in but at that link it showed i wasn’t).
2 - Type anything in the search box
3 - when the results page shows up… just go to brave browser settings and hit search engine
4 - Once in search engine, select standard tab (and private tab after if you want), at the >bottom you will see presearch listed (as used for a recent search). And then just select it >and now you can use it as your default search engine for any search on your mobile >browser.
In addition, the builtin ability to use a shortcut to search any site does not work either
Also, I’ll have to tell you that I have Index other search engines Automatically indexes websites that follow the OpenSearch spec. enabled at brave://settings/search
As a result, it already had placed Presearch into my search engines. So I didn’t even have to do the steps in the prior. Not sure if you have that enabled or disabled. Mine came disabled by default and I had to turn it on.
Now, when Presearch was added, it was stored under inactive, just as you can see in the screenshot below:
So I had to click Activate and then it appeared in options above. When I clicked to Edit it (the pencil icon), the default Shortcut wasn’t :p but was instead engine.presearch.com (which really isn’t a shortcut). So I had to edit that for :p to work. Saved it and everything worked perfectly.
