Searching for bumpworthy threads before the upgrade/archive, I try setting a value of 100 in the box "Find Threads with" ... "At Least" [ ] "Replies". It seems to be totally ignoring this option and returning threads in the search results that have less than 100 replies.
So then I see the "Sort Results by" options, so I can sort the threads in order of number or replies, descending. Right? Well no, that doesn't work either. Nor apparently does is sort threads by "Number of Views", "Last Posting Date" or even "Title"
