 I am trying to find all posts that are in the intersection of category x
 and tag a.  I would expect that this query to my blog would work:

 /?category_name=x&tag=a : Gives a 404 -- even though I have several items
 in category x && tag a.

 However, I have found that querying a single category with multiple tags
 does work:

 /?category_name=x&tag=a+b : Gives results of items in category x && tag a
 && tag b.

 As a work-a-round for my issue, I've found that this works:

 /?category_name=x&tag=a+a : Gives results of items in category x && tag a

 I found this work-a-round by searching through includes/query.php to see
 if I could troubleshoot the issue.  I'm not quite sure how to fix the
 issue, but it appears that
 tag=a uses a different query than tag=a+a ..

 I hope my explanation was easy to follow, but if not, I'd be glad to try
 to explain further, or provide an example on my blog.
