This is the perfect alternative for anybody who is wanting to escape Google's growing monopoly without moving to yet another company's service that does not really have any advantages over the last. This Open Source project first appeared in 2004 and still has an Alpha status on YaCy's SourceForge page — but don't let this fool you. YaCy runs on every (almost) every platform and features a built in web server which provides an excellent web based interface for both interactive searches and administration of your node (crawler).
Start the web indexer (you can restrict the indexing to your intranet too) to start at your blog, and away it goes indexing locally everything related to you. Searches which pull results from your local index perform at Google-esque speeds, although you might have to wait a few seconds for searches from distributed sources.
I have not brushed over even half the features and installation takes just a few seconds so trying it out for yourself is the best way to experience it!"
