In Stack Overflow, there is this search page, where I can do advanced searches such as
hasaccepted:0 user:me (- find all my questions without an accepted answer).
In Stack Exchange, there is also a search page, but it is different - it uses Google custom search, and the advanced search from above does not work.
Thus, there is no way to find all my questions without an accepted answer, in all sites.
Is there a way to do advanced search such as
hasaccepted:0 user:me, in all the Stack Exchange sites at once?
