I agree that having only one result for a thread is better.
I had a closer look and I think the problem is in the search::datasource implementation. The combined content of all messages of the thread should be indexed but the query to retrieve it is not correct:
<fullquery name="callback::search::datasource::impl::forums_message.messages">
<querytext>
select subject, content, format
from forums_messages
where message_id=:message_id
-- lets just get the message instead of the whole thread
-- replace with a connect by
</querytext>
</fullquery>
Thanks Dave. I'll fix that and try again.
