On Biblical Hermeneutics, we are trying to provide second opinions. It seems we can search for open questions with no answers:

answers:0 is:question closed:no

Or open questions with one or more answers:

answers:1 is:question closed:no

But we can't easily find the questions with exactly one (1) answer. Or at least, I haven't discovered a way to do that.

There is no way to do so. –  nhahtdh Jan 7 '13 at 15:07

@nhahtdh: Hmm... Sounds like I should turn this into a feature-request. –  Jon Ericson Jan 7 '13 at 15:08
    
That's a cool idea. (Providing a second opinion, I mean) –  Pëkka Jan 7 '13 at 15:09

@Pekka: I was hoping there was a not operator: answers:1 !answers:2. Nope! (Or rather, "not". ;-) Also, it seems answers:X turns on is:question, so we can shorten the URL a bit that way. –  Jon Ericson Jan 7 '13 at 15:12

I think the only way to conjure up such a query would be through the data explorer. –  Jeff Mercado Jan 7 '13 at 15:20

@JeffMercado: The data explorer doesn't cover beta sites. :( –  Caleb Jan 7 '13 at 15:28
    
@Caleb: Which is the unfortunate part. –  Jeff Mercado Jan 7 '13 at 16:42
    
+1, this would be an amazing thing to be able to do. Could probably be userscript'd though... –  Charles Jan 7 '13 at 19:01

So I was reviewing the revisions to the search announcement when something stuck out in rev 14:

  • New range support, here are some examples:
    • answers:1..1 (exactly one answer)
    • answers:10..20 (10 to 20 answers)

It totally works. Here are all open PHP questions with exactly one answer, which has not been accepted. You can also use the range operator for score, and probably all of the other things that are numbers. For example, here are all 24,000 PHP questions with negative scores, down to -100.

All Hail Elasticsearch!

There are only 24,000? –  Michael Berkowski Jan 8 '13 at 1:18
    
The cv-ring also issues delv-pls requests and are very aggressive about it. Questions with negative score are also routinely automatically pruned by the system. Here's the current low-score winner in PHP, at -14. –  Charles Jan 8 '13 at 1:19
    
As it turns out, I'd noticed that too. It looks like the notation has already been updated, but I'm sure when it's stable this will be the right answer and I'll get (my second) status-complete feature-request. –  Jon Ericson Jan 8 '13 at 17:04
