Hi,all

>Expose 0.8.0 distributed indexes as readonly column families which are sorted by the index
value, and which are queried using get_range_slices
i am wondering how to solve this query with the readonly index:
 email == 'bob@gmail.com' && (lastlogindate > today - 5 days || newmessagedate
> today -1 day).

since i met the similar problem: in SQL expression,it is like:
select * from sometable where author='somebody' order by last_reply_time desc.

or do i make some misunderstanding?

thank very much.

> For a lot of users paging is a standard use case on many web applications.  It would
be nice to allow paging as part of a Boolean Expression.
> Page -> start index
>            -> end index
>            -> page timestamp 
>            -> Sort Order
> When sorting, is it possible to sort both ASC and DESC?
