I've been studying and trying to understand the [original version](https://sqlite.org/forum/forumpost/e5392f9f6c?t=h). Thanks for this version. It works for me. On the network, I should be able to <i>:start</i> and <i>:end</i> at any available node. However, when I start at a <i>:start</i> node higher than the <i>:end</i> node, I am not getting any results with either version.
