Hi David,

Thanks for the feedback.  I removed hypertable-announce
<https://groups.google.com/forum/#!forum/hypertable-announce> from the
recipient list since this is more of a user mailing list question.
 Initially we were shying away from large scan queries against the
secondary indices, since a fairly innocuous query (e.g. WHERE tag < 'g')
could turn out to be very expensive -- worse than a full table scan (copy
half of the entire table into a temporary table ordered by the secondary
key and scan that temporary table).  However, since we've added prefix
queries, we may as well just go all the way and add the relational
operators and let users learn to be careful.  One thing I haven't figured
out is what the syntax might look like for relational operators against the
*qualifier* index.  Do you have any thoughts on that?

- Doug
