Quick question for searching

Hi, I'm already registered here for quite some time, but I never actually posted on the forums.
I have a question regarding searching by tags: Is it possible to search for more than one tag at a time? Like can I enter two tags (i.E. 'anal' and 'oral') and let it show me the doujins that are tagged with these?
If the question is already answered somewhere, I sincerely apologise.
Thanks in advance for the help :)
