I am happy to see the way that the site has evolved over time. It's great that so
many features brought up in this thread have found their way into use.
I remain hopeful for a way to tell search to exclude specific terms in the text fields.
For instance, if I wanted to find all of the doujin albums released at last month's
Comiket 78, I would make my selections as shown below. However, to further filter
my results to non-Touhou related albums, in the "Composer contains" field, I would
add the operator "NOT" to exclude the term following. Advanced search is already
powerful. With this additional level of specificity, it could become even more useful.
