What am I missing here? Unless I'm oversimplifying, it seems that what we
want is to do a query like "title=rabbit" and then get a summary breakdown
(number of titles) by author.
The summary could be requested and returned via
Or let the client do it. Search "title=rabbit", sort on author, define an
element set (i.e. schema) that consists of author only, retrieve the whole
result set according to that schema, and let the client create the summary.
Or retrieve the first N records (100, 1000, ...) create a summary from
those, then see if the user wants the next N records.
