From: Jonathan Ellis To: James Thornton Cc: cassandra-user@incubator.apache.org Content-Type: text/plain; charset=ISO-8859-1 X-Virus-Checked: Checked by ClamAV on apache.org Cassandra does not give you FTS or any secondary indexing out of the box. It's a pretty low-level API, but it will scale just fine if you want to build a FTS index out of it -- this is what facebook's first cassandra app was, and http://twitter.com/tjake is working on a Cassandra back end for Lucene which will be more general-purpose. There's links to some presentations facebook gave which cover their inbox search data model at http://wiki.apache.org/cassandra/ArticlesAndPresentations. -Jonathan On Tue, Sep 29, 2009 at 10:44 PM, James Thornton wrote: > Hi Jonathan - > > To what extent does Cassandra support full-text search?
