So the problem is that I can't seem to have a two-word tag in the advanced search field.

It doesn't seem to actually register it.

Were the tags comma separated ?

Are far as I can see in my code, up to 9 tags can be used in an Advanced Search if they are comma separated.

school uniform, pigtails, glasses
