First up, cool project! I think what could be cool would be if the README.md included screenshots or links to a short vid that demonstrates the basic_sample. It hits a bit more directly and inspires curiosity to want to fiddle around with stuff when you can just see it more directly work in practice :-D
As for search - The entire forum runs on an SQlite database and the search acts based on SQlite's full-text-search table feature FTS5. If you want to go for a bit of a dive, you can look in the repository for it for the relevant code: <https://github.com/nim-lang/nimforum> One of the limitations of FTS5 search is that it can't search for _suffixes_ well. You can work around that limitation, I've done so myself, but your FTS5 table must be set up to do so, it essentially doubles your FTS table size (not in rows, more in amount of data stored per row) and it does slow searches down a little (though not by a lot). So my guess is that you're just not going to get many hits because `Installer` does not match for `SnelInstaller`. Maybe for the next version make a thread `Snel Installer` or the like? That would work around that limitation as well.
