If I search for "dojo" on stackoverflow I'm taken to this page which displays only a single result for the tag.
However if I go into that single post it clearly lists on the right hand side that there are (at the time or writing) 574 posts with the "dojo" tag. If I then click on the tag again I'm taken back to the first page which announces that there is only one question with the dojo tag.
Am I missing something here?
Now obviously the problem is that I happened to have been on the featured tab when I did the search, so it searched within the featured questions. Just me being dumb.
