Using multiple tags at once

Would it be possible to implement a system where we can have multiple tags active in one search? This and the ability to filter certain tags out as well would make Fakku absolutely perfect for me.

Well this has been answered before.

There is no "official" multiple tags search but you can find works with multiple tags using the search bar at the top of the site.

For example you can type "oral pettanko"
All the results will show ones with both the tags "oral" and "pettanko". This also works for every tag. However if there are not enough works that include every tag in your search preference, the results will not show anything you desire.

Jacob has already said just recently that Fakku Gold will have a feature to filter tags on the very homepage

Oh, I didn't realise this. Thank you very much!

You can also omit tags using -. For example, "-oppai pettanko" will omit oppai but show doujins with pettanko.
