In the past, I used to have a blurb that said something like:

If you’re looking for something, you can search by keyword here. I can’t guarantee it’ll work, it’s kind of a best-effort thing.

But at some point I got my act together, realized I’m not a competent enough engineer to build my own search, and farmed out the job to someone who is. Which is all to say, the search should actually be pretty decent these days!
