Is There a Searchable Chant Database?

I'd like to find a database that can be used to answer questions like these:

What antiphons are used with psalm tone 4d?
Is that tone only found in old publications? (or What is the publication date of each?)
In those publications, what percentage of mode 4 antiphons use tone 4d?

Does GregoBase have any search features that can help with questions like these? Are there other resources that might help?
