i have a few questions about boost that might have been discussed and answered on this list before. there seems a convention to add the topic in square brackets to the subject as e.g. [thread], [preprocessor] or [review], etc. how do i search the list archive by these topics ? i see there is http://search.gmane.org/ but that only supports search by keywords in the entire message and seems to ignore [square brackets]. there is also custom google search on the boost homepage which i can further filter down to the mailing lists by adding site:lists.boost.org, but it also ignores square brackets, even when put in double quotes and does not seem to allow sorting by date or support a threaded display. lists.boost.org/Archives/boost/ doesn't support searching at all. is there a trick how to search the mailing list archives properly ?
