Whilst duplicate wikis are often seen as superfluous, I seriously doubt whether having a search function on homepage:Special:CreateNewWiki will help matters. As has been pointed out, people will often create a new wiki for no reason other than they want sysop tools and the current admins won't give them what they want. Do you really think searching for that wiki's subject is going to make them change their mind?

Another possibility is to request a wiki that has been abandoned with little to no content to be redirected to the more active wiki. Obviously, this won't work with wikis that are active but aren't as good as another on the same subject, but it might help reduce the number of empty sites.
