I'm attempting to implement session-based query caching for the Graves project, since it's the simplest and the first, so that I can use the approach in the other projects when it's perfected. There don't seem to be any clear working examples of this in the wild; the Shakespeare example caches only a single result set and as a consequence has bugs if you do multiple searches in different tabs. I have an approach mapped out, and I'm beginning to write code for it, but I'm a little surprised there are no examples of anyone else doing it. I'm pretty sure it'll be really quite important for speed and responsiveness in the larger projects.
