I have been struggling to do this since the tag was banned and would greatly appreciate any suggestions.
Please note: I do not want this search to be language specific.
I am assuming that you want posts that are would be considered beginner questions?
The answer is you can't. One of the reasons meta tags where banned, especially the beginner tag, was because everybody's idea of what a beginner question is, is completely different, and the tag held no value for anyone really. It also had a bit of a negative connection to it, and some users found it insulting when their questions where tagged beginner.
Every tag so far that people have tried to use to replace beginner has since been banned as well, and chances are this will keep happening going forward.
