No(or little) nodes,indexed sources,indexed keywords are saved when amule is down.
For me, amule took roughly a week to find ~30000 nodes or a day to find a few thousands, it wastes my time and resource on download, upload and get fewer search results.
Some node may go offline over time, so there should be a method to filter out and remove old nodes. The data(save nodes,indexed sources,indexed keywords) can be saved with timestamp, so the next time when amule is up amule can cleanup the dead(old) data. The diskspace required is worth-trading for the actual time that is noticeable and wasted.
