http://wiki.apache.org/cassandra/API#get_slice
get_slice retrieves the values for either (a) a list of column names or (b)
a range of columns, depending on the SlicePredicate you use.  It does not
allow you to filter a la SQL's WHERE.  You would need to create your own
index to do so, at least until secondary indices are implemented in
Cassandra (not until 0.8 at least, feel free to follow
https://issues.apache.org/jira/browse/CASSANDRA-749 )
