If Wikipedia had full-text search, with a results page that looked like Google, and it was as fast as Google, would you use it?
Consider that Wikipedia is not, AFAIK, collecting your search data to serve you advertisements.
I have found that there's very few Wikipedia pages I can't pull up with a Wikipedia "search" that I could only get with a Google search.
e.g. [your browser] http://en.wikipedia.org/wiki/search_term =one step
versus
[your browser] http://www.google.com/search?q=search_term then finding the right result and clicking it =two steps
