It was a joy to read this article. I'd love to know more on the nitty-gritty details of the implementation.

Are there any gotchas around the sql parameterization? Looks like you're passing in an array into db.exec. I would have thought that would be enough, but if I search for org-mode then I see an error on the console complaining about no such column: mode.

adding some quotes seems to help; you can search for e.g. "coe-xx-mode" and it will turn up results.

Is this an alternative to helm-swish?
