Drumknott is an excellent clerk, and cannot abide such malpractices as deliberate misfiling.

Drumknott provides hosted searching for your static Jekyll sites. All you need to do is connect things up via Javascript, and upload your page data to Drumknott's API. The documentation covers both steps in detail.
Each site costs $3 USD per month (which is GST-inclusive for Australian customers). If you'd like to see it in action before you pay anything, kick the tires on my blog's search page.
If you'd like to set up your Jekyll site to use Drumknott, create an account! — or sign in if you already have an account.
