My YaCy Installation
I mentioned YaCy, the distributed search engine, yesterday and managed to get a working prototype server online. If you're interested in trying it out you can do so by navigating your web browser here. As it currently stands I've only indexed this blog meaning most of the search results on the first page with be from here. Another thing to note is that crawling and indexing sites takes a notable amount of computing power so the search page becomes unresponsive during those operations (it'll throw a "504 Gateway Time-out" error).
Feel free to play with it and let me know what you think. I'll be tweaking it periodically throughout the week so it may be down from time to time. Also, I know the search results aren't going to be nearly as good as those provided by Google or Microsoft but it's a fairly young system and still growing. Right now you should just assume my setup is a prototype.
