Advanced search function

While browsing this site I came across the problem - I can only search mangas including one tag at a time. For example - if I want to find mangas with both oppai and vanilla, I have to search for titles with oppai tag and THEN look for those with vanilla tag by myself. Is it possible to add an "Advanced search" option, which would allow searching for mangas with more than one desired tag?

Wow, I had no idea. Thanks a lot!
