This is actually how our production search ranking is built for around the
top 20 sites by search volume that we host. Simple wikipedia isn't one of
those we currently use machine ranking for though. Because of that we do
have the data you need, but the problem will be that the actual search
queries are considered PII (Personally Identifiable Information) and not
something I can release publicly. It may be possible to release aggregated
data sets that don't include the actual search terms, but at that point I
don't think the data will be useful to you anymore.

I would love to base this on Simple Wikipedia data since it would fit well
