over the years we have received a ton of questions similar to this one:

How many words can be formed using all the letters of "DAUGHTER" so that vowels always come together?

They are all basically the same, they have a restriction that can be solved via some kind of casework.

Has such a list for this been made before?

This is a pretty good collection, and then there are more.

I think search is preferable to a list, as far as duplicates are concerned, because the extra restrictions vary: it can be something about containing or not containing a string, or ending/beginning, or not having vowels together, or length restrictions, etc. It's easier to add a relevant keyword to one of the above searches than browse a long list looking for similar restrictions.
