If you look in the number symbol column (sorry .. don't have one on my keyboard lol) You may have say 100 of the same file. This will only take up one line but show as 100 in the results count. Depending on how your junk filter is set (I don't have one so I'm not 100% sure) I think junk results may be included in the count, but may not be visible.
I hope this helps..If not please let us know
