buddycloud's search engine is up and running!

As the title says, we have put the search engine to work :)

The prototype returns data provided by the buddycloud team, that is a snapshot of their database. Available queries are for nearness, channel metadata and post content, besides channel recommendation for users and channel similarity. The syntax of these query (and responses) can be found at the Channel Directory protocol page.

The XMPP component is running at search.buddycloud.com. Please try it! Some examples of queries (and their semantics) follow on:
