Website mailing list search enhancement idea - one result per thread

Just an idea...

When searching the mailing lists in advanced search mode we have list
filtering, timeframe filtering (pretty coarse though) and then sorting
mode. For moderately long running threads a search term is going to return
many messages from the same thread. It would desirable to ask that only
threads be shown and maybe how many individual messages in that thread
matched. Going into the first message and then choosing "whole thread" (or
going directly to whole thread mode) would be the typical action by the
searcher who is looking to pull up a conversation they recall happened (or
assumed did) and can quickly skim the whole thing for context and
information.

Thanks for reading!
