Not too long ago I got fed up with how good a job Duckduckgo's site search feature wasn't doing. No matter what I did I couldn't find dick around here. And, folksonomies being what they are, unless you plan them (and then they won't be folksonomies) you probably won't remember what tags you used.

UPDATED: Added an Nginx configuration block to proxy YaCy.

If you've been squirreling away information for any length of time, chances are you tried to keep it all organized for a certain period of time and then gave up the effort when the volume reached a certain point.  Everybody has therir limit to how hard they'll struggle to keep things organized, and past that point there are really only two options: Give up, or bring in help.  And by 'help' I mean a search engine of some kind that indexes all of your stuff and makes it searchable so you …
