Reply To: Protected replies are shown in Search results
Trying to reproduce your issue and I cannot reproduce it accurately, if I search for a password protected topic I actually see both the topic and the reply in the search results, you should also see both.
I presume you are creating these (or protecting them after the fact) in the backend?
(/wp-admin/edit.php?post_type=topic), what I assume should be the case is that if you are manually protecting the topic you should manually protect the replies (/wp-admin/edit.php?post_type=reply) also.
In short bbPress doesn’t support password protected forums, topics & replies officially, yet. There is ‘some’ support in the backend and partially in some of the templates but we haven’t got ‘all of it’ in bbPress yet.
You will also have issues when browsing the topics via eg http://example.com/topics/ and not see the actual topics list. There are probably a few more places where this will break also.
Create a ticket on trac to remind us to look at this for a future bbPress release.
(It will also act as a subtle reminder to keep it in mind whilst other code is written)
