Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I couldn't find a similar question, forgive me if this is a duplicate. To illustrate the problem, I'll use the following example on SO:

We previously had java-ee, java-ee-5, java-ee-6 questions so I have java-ee* in my list of interesting tags which is translated into (java-ee or java-ee-5 or java-ee-6).

But java-ee-5 and java-ee-6 questions have been retagged now and java-ee is the only tag left. The problem is that (java-ee or '') returns 0 questions while there are many (504+) questions with the java-ee tag.

IMO, should return the 504+ questions as well.

confirm. the link you give returns 0. this link ( gets all of them; note the single-character difference. (oops, except it also gets a few other tags. not quite as useful as i thought.) – quack quixote Mar 27 '10 at 11:44
@quack Indeed, but as you noticed java-e~ matches more than one tag. The bug is when there is only one match. – Pascal Thivent Mar 27 '10 at 12:49

There was an extra "or" being added to the end of the wildcard explode operation, which was preventing the single result case from working. Should be fixed now.
