I use the Pelican static site generator for this site. A static site generator is a way to pre-build all of the content for a web-site. This provides faster page downloads, lower server requirements, and better security for the site.
I was using the Tipue Search plug-in to provide search for the site. I learned that particular plug-in has been deprecated and has been replaced with a different search plugin that promises to be much faster.
The bad news is that I need to modify the templates I use for this site in order to get it to work properly. So, that is a bit of a work in progress.
Fortunately, this site is not complex and my posts are are in the four main categories. The other nice thing is that the tag cloud on the right side-bar helps to filter down the articles quite nicely.
