The advanced search keywords include “closed:yes” and “closed:no” for searching for questions that are closed and not closed, respectively. Now that there is a new status, [on hold], is there a search term for such questions? At the moment, it seems that “closed:yes” includes questions that are [on hold], as this search illustrates: “[html] [xml] [rdf] closed:yes”. I think that this question makes it clear that [on hold] questions appearing for “closed:yes” is intentional.
If there is any way for [on hold] questions to become [closed], other than the five day waiting period, it seems like it would be useful to be able to search for [on hold] questions without the [closed] questions.
I'm wondering whether there is a search term for [on hold] but not [closed] yet. The advanced search tips don't show anything for it yet, but perhaps the tips just haven't been updated yet.
